白光发光装置
摘要：
本发明公开了一种白光发光装置，包含：一激发光源；以及一磷酸盐荧光材料，其组成为(Ca1-x-yMyEux)2PO4N或(Ca1-xEux)2PO4N，其中M包括Mg、Sr、或Ba，N包括F、Cl、Br、OH、或上述之组合，0.01≤x≤0.20，且0＜y≤0.8；以及一蓝光以外的荧光材料；其中该激发光源用以激发该蓝光磷酸盐荧光材料以放射波长介于410nm至500nm的蓝光。此磷酸盐荧光材料经由激发后可放射出蓝光，与其它适用的非蓝光荧光材料组合可作成白光发光装置。
摘要（英）：

The invention discloses a white light-emitting device comprising an excitation light source and phosphate fluorescent materials, the composition of which is (Ca1-x-yMyEux)2PO4N or (Ca1-xEux)2PO4N, wherein M includes Mg, Sr or Ba; N includes F, Cl, Br, OH or the combination of the F, C1, Br and OH, 0.01 is less than or equal to x which is less than or equal to 0.20 and 0 is less than y which is less than or equal to 0.8; and fluorescent materials besides the blue lights; the excitation light source is used for exciting the light-light phosphate fluorescent materials to radiate the blue lights with wavelengths between 410nm and 500nm. After being excited, the phosphate fluorescent materials can radiate blue lights and can be made into white light-emitting device combining with other applicable non-blue-light fluorescent materials.
