摘要
固体白光照明节能省电、无污染、长寿命,是替代白炽灯和荧光灯的新一代半导体光源。介绍了白光LED的产生、优点和研究现状,以及与之相匹配的稀土发光材料的研究动态,主要包括蓝光、紫外光和近紫外光转换型荧光粉,并介绍了新型单一相白光LED荧光粉和新型荧光体的发展状况,最后分析和评述了我国白光LED的差距和发展前景。
Solid state lighting is a new semiconductor lighting source,which takes advantage of the energy saving, no-pollution and long lifetime. The develpment of the white light LED and rare earth phosphors for LED, including phosphors of emission blue, purple and near ultraviolet light, is summarized.
