穩定螢光碳量子點凝膠玻璃於環保發光太陽能聚光器之應用

發光太陽能聚光器(Luminescent Solar Concentrators, LSCs)由螢光體和波導所組成，目前擁有好的光物理性質之膠體螢光材料多是含有重金屬以及有毒的有機溶劑。而屬於環保材料的碳量子點(Carbon dots,CDs)又會有濃度誘導淬滅(Concentration-induced quenching,CIQ)和易產生聚集誘導散射(Aggregation-induced scattering,AIS)的問題。同時現今運用在LSC上的高分子材料則有在UV長時間照射或受熱會破壞其光物理特性及吸濕後會易水解等問題存在。因此本研究以耐熱性與穩定性皆佳之矽烷基高分子與碳量子點鍵結，並選擇不同種類官能基之silane (-NH2、-NCO、-CH3)與碳量子點反應，進一步探討其光物理特性，找出最佳條件以做為發光太陽能聚光器之應用。

Luminescent Solar Concentrators, (LSCs) are composed of loaded luminophores and glass waveguides designed to efficiently harvest both incident and diffused solar irradiation devoid of complex solar tracking system. However, most of reported LSCs bank on on colloidal fluorescent materials with noble photophysical properties are frequently comprised of heavy metals and toxic organic solvents. In lieu of this, it is necessary to search for nanomaterials with excellent photo physical, yet considered to cause minimal harm to environment and human health. Carbon Dots (CDs) are environmental friendly nanomaterials but suffers from minimal problems such as concentration-induced quenching (CIQ) and aggregation-induced scattering (AIS). At the same time, the polymer materials used in LSC today have disadvantages such as long-term UV irradiation or heating, which will destroy the photophysical properties and easily hydrolyze the samples after moisture absorption.Therefore, in this study, sulfonated alkyl polymers with excellent heat resistance and stability were bonded to carbon quantum dots, and silanes (-NH2, -NCO, -CH3) with different functional groups, and were selected to react with carbon quantum dots to further explore their light-harvesting properties. The photophysical properties of the CDs used in this research was investigated in order to find the best and optimized conditions for further utilization as a luminescent solar concentrator.
