一种用于光学波长转换的荧光玻璃涂层及白光发光装置
摘要：
一种用于光学波长转换的荧光玻璃涂层的制造方法，玻璃基板A上烧结制备荧光体C与玻璃B粉末的混合层：（1）将质量比为100:1－100:150的玻璃B的粉末与荧光体C的粉末、粘结剂和溶剂混和成均匀的糊状物；玻璃B和荧光体的粉末的粒径在1微米到60微米之间；（2）将糊状物均匀涂覆在玻璃基板A上，将涂有糊状物的玻璃基板A干燥，使溶剂挥发完全；（3）将干燥后的涂有糊状物的玻璃基板A烧结，在玻璃基板A表面得到含有荧光体的玻璃B涂层；步骤（3）中，荧光玻璃涂层的烧结温度高于玻璃B的玻璃化转变温度。
摘要（英）：

The invention discloses a method for manufacturing a phosphor glass coating for optical wavelength conversion, which comprises the step of sintering and preparing a mixed layer of the powder of a phosphor C and glass B on a glass substrate A, specifically: (1) mixing the powder of the glass B and the phosphor C at a mass ratio of (100:1)-(100:150), binder and solvent into uniform paste, wherein the particle size of the powder of the glass B and the phosphor is 1-6 microns; (2) uniformly coating the paste on the glass substrate A and drying the glass substrate A coated with the paste to make the solvent volatilize completely; and (3) sintering the dried glass substrate A coated with the paste to obtain a glass B coating with the phosphor on the surface of the glass substrate A, wherein the sintering temperature of the phosphor glass coating is higher than the conversion temperature of the glass B in step (3).
