摘　　要：绿光转换材料是激光投影显示的核心部件,然而目前适用于高品质激光显示的高性能窄带绿光转换材料仍较为短缺。为此,将商用窄带绿色β-SiAlON∶Eu^(2+)荧光粉与基于新型玻璃组分的低熔点玻璃以薄膜形式共烧结在蒸镀一维光子晶体膜的高导热蓝宝石基片上,形成一体化微晶玻璃薄膜复合材料。研究表明,经低温共烧β-SiAlON∶Eu^(2+)受玻璃组分热侵蚀不显著,复合材料荧光内量子效率为55%,半峰全宽为54 nm,150℃时荧光积分强度仍保持室温下的90%左右;一维光子晶体膜大幅增强了绿光前向发射强度约1.5倍;材料在蓝光激光功率密度达到9 W/mm2时,产生发光饱和,对应光通量为492 lm;并初步探讨了发光饱和机理;耦合红色激光后,色域达到95.6%NTSC。The green color-converted materials are the core components of laser projection display.To date,the highperformance narrowband green color-converted materials for high-quality laser display are still in short supply.In this paper,the commercial narrowband green-emissiveβ-SiAlON∶Eu^(2+)phosphor together with a kind of low-melting-glass of new composition are co-sintered on a high thermal conductivity sapphire substrate coated by one-dimensional photonic crystal film,forming an integrated phosphor-in-glass film composite.It is demonstrated that the thermal erosion ofβ-SiAlON∶Eu^(2+)is insignificant after low temperature co-sintering.The composite material exhibits the internal quantum efficiency of 55%,full width at half maximum of 54 nm,and excellent resistance to thermal quenching(the integral luminescence intensity at 150℃remains about 90%of that at room temperature).It is also found that the one-dimensional photonic crystal film greatly enhances the forward green luminescence up to about 1.5 times.The luminescence saturation takes place under 9 W/mm2 blue laser irradiation with the corresponding luminous flux of 492 lm,and the latent luminescence saturation mechanism is tentatively analyzed.After coupling with red laser diodes,the color gamut reaches 95.6%NTSC.
