摘要

面向市场对高功率照明的强烈需求，兼具优良光学和热/化学稳定性的全无机荧光玻璃陶瓷正蓬勃发展。本文基于低温共烧技术制备了一种镶嵌La

:Ce

（LSN:Ce）荧光粉的硅基氮化物玻璃陶瓷荧光转换材料。研究表明，共烧时玻璃组分对LSN:Ce荧光粉侵蚀作用较小，荧光粉结构未受明显破坏，因而其荧光特性基本得以保持——量子效率为79%，150℃下荧光积分强度仅下降~14%。构建的高功率白光LED光源在350 mA电流驱动下，光效为54.8 lm/W，色温为5 712 K，显指为70.1，色坐标为（0.328 0，0.369 0）。构建的激光照明光源在0.8 W蓝光激光激发下，光通量为118.48 lm，色温为7 427 K，显指为56.2，色坐标为（0.298 2，0.322 6）。我们推断，在高功率蓝光激光激发时，LSN:Ce荧光玻璃陶瓷中发生了热饱和与光饱和现象。经进一步的材料组分、制备工艺以及器件结构优化，LSN:Ce荧光玻璃陶瓷可望应用于高功率照明领域，如汽车大灯和探照灯等。

Abstract

Towards the strong market demand for high power lightings

the all-inorganic fluorescent glass ceramics with excellent optical property and thermal/chemical stability are booming. In this work

a silicon-based nitride glass ceramic fluorescent conversion material embedded with La

:Ce

(LSN:Ce) phosphor was prepared based on a low temperature co-sintering method. It was demonstrated that LSN:Ce phosphor was less corroded by glass components during co-sintering

with its structure showing no obvious change

and so

good luminescent properties were retained with quantum efficiency of 79% and fluorescence integral intensity decreased only by ~14% at 150 ℃. The fabricated high-power white LED lighting source yields luminous efficacy of 54.8 lm/W

CCT of 5 712 K

CRI of 70.1

and chromaticity coordinate of (0.328 0

0.369 0)

upon 350 mA current driven. The constructed laser lighting source yields luminous flux of 118.48 lm

CCT of 7427 K

CRI of 56.2

and chromaticity coordinate of (0.298 2

0.322 6)

under 0.8 W excitation power. It was speculated that the thermal and light saturation phenomena occur in LSN:Ce fluorescent glass ceramics upon high-power blue laser excitation. After further optimization of material composition

preparation process

and device structure

LSN:Ce fluorescent glass ceramics are expected to be applicable to high-power lighting fields

such as automobile headlights and searchlights

and so on.
