Laser phosphor display technology plays an important role in advanced display projection; however, it is a challenge in maintaining excellent color accuracy under high brightness due to the lack of red spectrum. Here, red-emitting MgAlSiO:Eu ceramics as the phosphor wheel have been optimized in chemical compositions and texture orientation. The textured MgAlSiO:Eu ceramics have high transparency and spot limiting ability, accordingly, the ceramic wheel outputs 1,184 lm of ultra-bright red light under 50 W/mm laser power density. Moreover, the red spectral utilization (over 600 nm) of textured MgAlSiO:Eu ceramics is 2.17 times that of traditional YAlO:Ce phosphor wheel. The red-emitting textured MgAlSiO:Eu cordierite ceramic herein enables an improved light-color saturation experience, and it is potential in the next-generation laser phosphor display applications.

用于激光荧光粉显示的红光 Mg2Al4Si5O18:Eu2+ 陶瓷的 Si/Al 序和织构取向优化


激光荧光粉显示技术在先进显示投影中发挥着重要作用；然而，由于缺乏红色光谱，在高亮度下保持出色的色彩精度是一个挑战。在此，作为荧光粉轮的发红光 MgAlSiO:Eu 陶瓷在化学成分和织构取向方面进行了优化。织构化的 MgAlSiO:Eu 陶瓷具有高透明度和光斑限制能力，因此陶瓷轮在 50 W/mm 激光功率密度下可输出 1,184 lm 的超亮红光。此外，织构化 MgAlSiO:Eu 陶瓷的红色光谱利用率（超过 600 nm）是传统 YAlO:Ce 荧光粉轮的 2.17 倍。本文中的发红光织构化 MgAlSiO:Eu 堇青石陶瓷能够改善光色饱和度体验，并且在下一代激光荧光粉显示应用中具有潜力。
