高亮度激光荧光光源用双面蓝宝石基荧光玻璃膜制备及其光热性能
Fabrication and Photothermal Performances of Double-sided Phosphor-in-glass Film for High-brightness Laser Lighting
摘要
Abstract
The development of color converters with high luminescence saturation thresholds presents a critical challenge for next-generation high-brightness laser lighting technology.In this work,a novel transmissive Y3Al5O12∶Ce3+(YAG)phosphor-in-glass film(PiGF)featuring a double-sided sapphire sandwich structure(S@PiGF@S)was designed and fabricated via thermocompression sintering.This configuration significantly enhances tolerance to high laser power density through efficient dual-side heat dissipation and a"photothermal-decoupling"effect.Experimen-tal results show that the optimized S@PiGF@S color converter achieves a luminous flux of 2 761 lm at 16.6 W·mm-²,representing a 125.3%improvement over the conventional PiGF@sapphire structure(1 205 lm at 8.5 W·mm-²).More importantly,by incorporating a rotational dynamic cooling mechanism,the core temperature remains as low as 47℃even under a laser power density of 18 W·mm-².These findings confirm that the S@PiGF@S converter exhibits outstanding opto-thermal performance,demonstrating great potential for applications in high-brightness laser lighting.关键词
