英文摘要Obtaining high luminance light source by emitting and excitation of blue-emitting laser diodes(LDs) has become an important research direction in the field of high-power lighting and display. This field involves multiple disciplines including luminescent materials, optical engineering, mechanical structure and circuit design, among which optical design and color conversion materials and devices are key technologies. Due to their high research and production expenditure, they have become one of the factors limiting the realization of large-scale and widespread applications. In this paper, the rapid and low cost preparation of Ce3+:Y3Al5O12-Al2O3(Ce3+:AY26)based phosphor nanoceramics by pneumatic suspension solidification was studied. The luminescence performance was optimized by adjusting Ce3+ doping concentration for achieving higher quantum efficiency (87.4%). As the second phase, Al2O3 not only can play the role of scattering center and improve the conversion efficiency and beam uniformity of laser excitation, but also has higher thermal conductivity, which plays a key role in improving the thermal stability, and Ce3+:AY26 phosphor nanoceramics still hold 95% of room temperature quantum efficiency when temperature reached 200 . Through the transmission laser illumination test system, the optical and color properties of 1.5 mm thick phosphor nanoceramics sheet with LE of 174 lm鈥-1 and 1.5 mm semispherical phosphor nanoceramic under high power density blue laser irradiation were studied. Hemispherical phosphor nanoceramics prepared by containerless solidification technology are expected to simplify the optical structure design of transmission laser illumination modules from the point of view of material preparation methods and have great application potential in the future. 漏 2021, Science Press.
