“节能减排,保护环境”是目前全人类一个共同的发展主题。在世界各国和地区,照明用电占据着其总发电量的显著比例。相比于传统的照明光源(白炽灯,荧光灯,高压气体放电灯等),发光二极管(light-emittingdiode,LED)作为新一代的照明光源有着诸多优点,如寿命长,效率高,无重金属污染,以及结构紧凑,易于设计、安装、运输等。基于蓝光芯片的白光LED是目前市场的主流,此方案需要波长转换材料(荧光材料)使其产生白光。 铈掺杂钇/镥铝石榴石(cerium-dopedyttrium/lutetiumaluminumgarnet,YAG:CeandLuAG:Ce)是白光LED产业重要荧光材料,因其...Recently, “energy saving and emission reduction” are hot topics in human society. Among the world’s nations and areas, electric consumption on lighting accounts for a considerable proportion of the gross generation. Compared with conventional lighting sources (e.g., incandescent, fluorescent and metal halogen lamps), the light-emitting diodes (LEDs) are energy-saving, mercury-free, compact, and lo...学位:工学博士院系专业:材料学院_材料学学号:2072013015364
