Abstract

LuAG:Ce (LuAlO:Ce) is one of the most important color converters in white lighting industry. Especially, LuAG:Ce film attracts more attention due to the outstanding advantages, such as the efficient heat dissipation, the saving of rare earth, and so on. Here, LuAG:Ce film on sapphire was successfully prepared by the ultrasonic spray pyrolysis process. The phase, microstructure and photoluminescence of LuAG:Ce films were investigated. LuAG:Ce films had a thickness of around 5 μm, which were well crystallized at 1000 °C in air atmosphere to form the typical garnet structure. Under the protection of CO atmosphere, increasing the annealing temperature greatly enhanced the photoluminescence performance. After annealing at 1500 °C for 5 h in CO atmosphere, 3.0 mol.% Ce doped LuAG:Ce film exhibited the highest emission and excitation intensity. The emission intensity of 3.0 mol.% Ce doped LuAG:Ce film annealed at 1500 °C in CO atmosphere increased up to five times, when compared with the best LuAG:Ce film annealed at 1000 °C in air atmosphere. The effects of Ce doping concentration on the photoluminescence were also examined. As the Ce doping concentration increased from 0.2 mol.% to 7.0 mol.%, the color of LuAG:Ce films changed from yellowish green to greenish yellow. When coupling the 3.0 mol.% Ce doped LuAG:Ce film with a 0.5 W 450 nm blue laser, the formed device successfully emitted white light.

摘要

LuAG:Ce(LuAlO:Ce)是白色照明行业中最重要的颜色转换材料之一。特别是,LuAG:Ce薄膜因其高效散热、节省稀土等突出优点而备受关注。在此,通过超声喷雾热解工艺成功制备了蓝宝石上的LuAG:Ce薄膜。对LuAG:Ce薄膜的相、微观结构和光致发光进行了研究。LuAG:Ce薄膜厚度约为5μm,在空气气氛中1000℃下良好结晶,形成典型的石榴石结构。在CO气氛保护下,提高退火温度可大大增强光致发光性能。在CO气氛中1500℃退火5h后,3.0mol.%Ce掺杂的LuAG:Ce薄膜表现出最高的发射和激发强度。与在空气气氛中1000℃退火的最佳LuAG:Ce薄膜相比,在CO气氛中1500℃退火的3.0mol.%Ce掺杂的LuAG:Ce薄膜的发射强度提高了五倍。还研究了Ce掺杂浓度对光致发光的影响。随着Ce掺杂浓度从0.2mol.%增加到7.0mol.%,LuAG:Ce薄膜的颜色从黄绿色变为绿黄色。当将3.0mol.%Ce掺杂的LuAG:Ce薄膜与0.5W 450nm蓝色激光耦合时,所形成的器件成功发射出白光。
