20220926 website  PRI member secures a Key Program Funding from the National Natural Science Foundat

PRI member awarded Key Program Funding from the National Natural Science Foundation of China (NSFC)

A project led by Prof. Hao Jianhua, Member of the Photonics Research Institute (PRI), was recently awarded Key Program Funding support from the National Science Foundation of China (NSFC). Prof. Hao will collaborate with the researchers from Nankai University and Sichuan Normal University to perform the study of multifunctional ultrathin ferroelectric integrated materials and devices for neuromorphic computing and artificial visual system. Artificial intelligence (AI) is a frontier field with significant societal impact. However, existing technologies cannot adequately meet future needs in terms of information transmission bandwidth, power consumption, processing speed and intelligent control. Particularly, the rapid development of neuromorphic computing and artificial vision system requires innovation solutions for multifunctional integrated materials and devices. Building on Prof. Hao's internationally recognised works on ferroelectric optoelectronics and the ferroelectric manipulation of rare-earth-doped luminescence, the proposed study is to effectively integrate ferroelectric polarisation with multifunctional characteristics of electronic properties of semiconductor, photodetection and rare-earth ion luminescence, to develop multimodal and novel synaptic devices. The developed materials and devices in this project will help overcome the bottleneck in information technology development.

20220923 Website  PRIs research achievement multiple exciton generation in tinlead halide perovskite

PRI research achievement: multiple exciton generation in tin-lead halide perovskite nanocrystals for photocurrent quantum efficiency enhancement

An interdisciplinary team led by Dr Li MingJie of the Photonic Research Institute (PRI), recently developed high-quality halide perovskite nanocrystals with enhanced multiple exciton generation (MEG). Nanocrystals (also known as quantum dots) developed from rational design can convert a high-energy photon into multiple electron-hole pairs, breaking the power conversion efficiency limit. The team successfully demonstrated for the first time that the internal quantum efficiency exceeded 100% at a low threshold, with the use of perovskite nanocrystals. The findings have been published in the highly influential journal Nature Photonics. Dr Li’s research has deepened our understanding of the MEG mechanism and provided valuable solutions for developing highly efficient light-harvesting techniques, including photovoltaics, photon detection, and solar-fuel production.

20220915 Website  - Recap PAIR Distinguished Lecture Series 220906

The third lecture of the PAIR Distinguished Lecture Series was successfully held on 6 September 2022

The third lecture of the PAIR Distinguished Lecture Series was successfully held on 6 September 2022. We were honoured to have invited renowned scientist, Prof. Li Deren, Academician of the Chinese Academy of Sciences, Academician of the Chinese Academy of Engineering, Member of the International Eurasia Academy of Sciences, and Professor of State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS), to be the distinguished speaker.  The webinar was hosted by Prof. Christopher Chao, Vice President (Research and Innovation) and Chair Professor of Thermal and Environmental Engineering of The Hong Kong Polytechnic University (PolyU).  It attracted over 300 participants from 24 countries and regions on Zoom, as well as over 18,000 online viewers on online-streaming channels.  Honourable participants include: (In alphabetical order of their last names) Prof. Fuu Jen Tsai, Provost of China Medical University, Taiwan         Prof. Christian Wagner, Provost of City University of Hong Kong Prof. Richard K Yuen, Chief-of-Staff of City University of Hong Kong Prof. Qingyan Chen, Director of PolyU Academy for Interdisciplinary Research (PAIR), Chair Professor of Building Thermal Science in the Department of Building Environment and Energy Engineering of PolyU, briefed the audiences on the establishment of PAIR and the Academy’s determination to address societal challenges and contribute to the achievement of the United Nations (UN) Sustainable Development Goals (SDGs). At the opening, Prof. Christopher Chao expressed that “the research works of Prof. LI provide special meaning to PolyU’s research developments.  As our two research institutes under the PolyU Academy for Interdisciplinary Research (PAIR), namely, the Research Institute of Land and Space (RILS) and Research Institute for Artificial Intelligence of Things (RIAIoT), are working on research projects in areas like land analytics and management and big data analytics with artificial intelligence technologies, and the generation of new solutions which essentially involve the fusion of geospatial information system (GIS) and internet of things (IoT) towards our goal for a more liveable and sustainable city.”  Prof. Li began the lecture by introducing the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS) at Wuhan University.  He presented an overview of LIESMARS’ history, research focus and directions, organisational developments covering human resources, facilities, research, publications, industrial and international cooperation, education programmes, laboratory’s awards, rankings, and recognition. Subsequently, Prof. Li gave a summary of the emerging trends in GIS in the era of IoT.  He highlighted the characteristic application of communication network infrastructure (5G, IoT, industrial internet, and satellite internet), new technology infrastructure (AI, cloud computing, blockchain), and computing technology (big data, intelligent computing) in different GIS-related areas, such as surveying, mapping, and remote sensing, for the study of people, places, nature, and processes of the earth. Super high-speed cyberspace modelling is the current development trend in GIS. Prof. Li further elaborated on the five characteristics of GIS in the era of IoT.  First, satellite positioning technology will move from the Global Positioning Satellite System (GNSS) to the Positioning, Navigation and Timing (PNT) system, and further to the Positioning, Navigation, Timing, Remote Sensing, and Communication (PNTRC) system.  Second, remote sensing technology will elevate from the Earth Observation Satellite (EOS) to the Earth Observation Brain (EOB), an intelligent earth observation system. Third, GIS’s map database will be developed to enable accurate 3D imaging and digital twinning.  Fourth, integrating GIS, RS and GNSS for mobile mapping and measurement will bring intelligent robot services.  Finally, GIS that focuses on observing earth processes and environmental changes will later emphasize the observation of human and related activities, such as car flow, heat maps, people flow, etc. Prof. Li then discussed three scientific issues of GIS in the era of IoT afterward.  He pointed out the need for map product that serves the needs of both humans and robots, the technical bottleneck of choosing between classification and semantic description for remote sensing image intelligent interpretation, and the need for geographic big data mining to support sustainable human development in harmony with nature. Prof. Li concluded with his final remarks and advice that future developments in GIS should leverage IoT to provide real-time data, develop smart GIS, explore the value of big geographic data, and adopt GeoAI for a more brilliant earth. The lecture was followed by a fruitful 30-minute discussion, moderated by Prof. Christopher Chao and joined by two panellists, Prof. Chen Qingyan and Prof. Weng Qihao, Associate Director of Research Institute for Land and Space and Chair Professor of Geomatics and Artificial Intelligence at PolyU.  Please click here for an online review.
