采用结晶法和低温共烧结法制备了Eu3+掺杂的Y3Al5O12∶Ce3+荧光玻璃, 对制备出的样品进行能量色散X射线谱和光致发光光谱测试, 表明稀土离子Eu3+与YAG∶Ce3+荧光粉已掺入荧光玻璃。掺杂不同含量Eu2O3的YAG∶Ce3+荧光玻璃封装成的激光照明器件在驱动电流100 mA下, 经过STC-4000快速光谱仪和PMS-80可见光谱分析系统测试, 掺杂质量分数1% YAG∶Ce3+复合质量分数9% 的Eu3+的荧光玻璃封装的激光照明器件发光效率为267.1 lm/W。激光照明器件随着电流的增加, 其显色指数逐渐增大, 但增加幅度较小。

The Eu3+ doped Y3Al5O12∶Ce3+ phosphor-in-glasses(PIGs) was prepared by crystallization and low temperature co-sintering. The prepared samples were tested by energy dispersive X-ray and photoluminescence spectroscopy, indicating that the rare earth ions Eu3+ and YAG∶Ce3+ phosphors have been incorporated into the PIG. YAG∶Ce3+ PIG with different content of Eu2O3 is packaged in a laser illumination device with a driving current of 100 mA. It is tested by STC-4000 fast spectrometer and PMS-80 visible spectrum analysis system, doping mass fraction 1% YAG∶Ce3+ composite mass fraction 9% Eu3+ phosphor-in-glasses encapsulated laser lighting device luminous efficacy is 267.1 lm/W. As the current of laser illumination devices increases, the color rendering index increases gradually, but the increase is small.
