英文摘要： The proposal of this project is to carry out the fundamental investigation on the materials and fabrication techniques of rare-earth (RE) ions doped downconversion quantum cutting and upconversion optical materials and related photonics devices for enhancing energy transfer efficiency of silicon-based solar cells. This project will focus on the fundamental investigation of fabrication, structural and optical properties, physical and chemical of materials, downconversion and upconversion luminescence of RE-doped nano- and micro- luminescent materials, and as well as RE-doped glass-ceramics. To obtain efficient downconversion quantum cutting and upconversion materials, systemically investigation on crystallization and homogeneous distribution characteristics as well as spectral properties of RE-doped luminescent materials and glass-ceramics will be empolyed. Meanwhile, the feasibility of application of the RE-doped downconversion and upconversion materials for enhancing energy transfer efficiency of silicon-based solar cells, and the basic scientific methods of fabrication techniques and applications involved will also being investigated and discussed. It is expected that this research could help researchers to better understand the physical mechanism of luminescence, and could promote the development of RE-doped optical materials and related photonics devices, and thus could provide theoretical and technological supports for related high-tech industries.
