摘要

以高折射率铅硅酸盐玻璃和YAG:Ce和SiAlON粉末为基材，研制并合成了复合材料“玻璃中磷”。为了减少玻璃/荧光粉界面上的散射，对玻璃成分进行了优化。采用玻璃粉和荧光粉在600℃下烧结的方法制备了白光led复合光转换材料样品。研究了复合材料的光谱、发光和结构性能。所获得的基于复合玻璃荧光粉材料的白光led已经进行了测试。测得探头LED的色温为4370k，光效为581m/W。

Phosphor in glass based on high refractive index glasses for LEDs

Composite “phosphor-in-glass” based on high refractive index lead-silicate glass and YAG:Ce and SiAlON powder has been developed and synthesized. Glass composition optimization in the order to reduce scattering at glass/phosphor interfaces has been performed. Samples of composite light-converting materials for white LEDs were prepared by sintering glass powders and phosphor at 600 °C. Spectral, luminescent and structural properties of the obtained composites have been investigated. White LEDs based on the composite glass phosphor materials obtained have been tested. The color temperature of the probe LED was found to be 4370 K with the luminous efficacy 581m/W.
