US20080017875A1 Yellow Emitting Phosphor And White Semiconductor Light Emitting Device Incorporating The Same 审中-公开
黄色发光荧光粉和白色半导体发光器件

Yellow Emitting Phosphor And White Semiconductor Light Emitting Device Incorporating The Same
Abstract:
The present invention relates to a yellow phosphor represented by a general formula of A(1-y)3D5-x Ex O12:Cey (wherein: A is at least one element selected from the group consisting of Y, Lu, Sc, La, Gd and Sm; D is at least one element selected from the group consisting of Al, Ga and In; E is at least one element selected from the group consisting of B and Fe; 0≦x
Abstract(Chinese):

本发明涉及一种由通式A（1-y-3）3-D-5-x-E-N代表的黄色荧光体， （其中：A为选自Y，Lu，Sc，La，Gd和Sm中的至少一种元素） ; D是选自Al，Ga和In中的至少一种元素; E是选自B和Fe中的至少一种元素; 0 <= x <0.5;并且0.0001 <= y <0.5） 和包含该半导体发光器件的白色半导体发光器件。 白色半导体发光器件包括半导体发光二极管和磷光体涂层。 荧光体涂层包括黄色荧光体和任选的基于硒的硒基红色荧光体，其吸收半导体发光二极管发射的光的一部分并发射与吸收光的波长不同的光和透明树脂。 白色半导体发光器件具有优异的显色性，并且在长时间的使用中仅具有非常低的发光效率劣化程度。
