Full-spectrum multilayer composite fluorescent ceramic with high thermal stability for laser illumination
The invention provides full-spectrum multi-layer composite fluorescent ceramic with high thermal stability for laser illumination. The full-spectrum multi-layer composite fluorescent ceramic is of a four-layer composite structure in total. The fourth layer is a ceramic chip prepared by mixing AlN and glass powder; the third layer is a main light-emitting layer and is PiG fluorescent ceramic formed by mixing yellow fluorescent powder, glass powder and a small amount of AlN; the second layer is a red fluorescent film and a green fluorescent film; and the first layer is an Al2O3 film prepared by magnetron sputtering. Due to the existence of AlN, the thermal stability of the ceramic is greatly improved, the full-spectrum illumination of the fluorescent ceramic is realized through the preparation of red and green films, the adhesive force of the fluorescent film is enhanced through the preparation of the Al2O3 film, the overall wear resistance and corrosion resistance of the fluorescent ceramic are enhanced, and the thermal stability is further enhanced.
本发明提供了一种具有高热稳定性的激光照明用全光谱多层复合荧光陶瓷，总共为4层复合结构；第四层是AlN和玻璃粉混合制备的陶瓷片；第三层为主要发光层，为黄色荧光粉、玻璃粉和少量AlN混合的PiG荧光陶瓷；第二层为红色荧光薄膜和绿色荧光薄膜；第一层为磁控溅射制备的Al2O3薄膜。由于AlN的存在，使得陶瓷的热稳定性大幅度提升，通过红色、绿色薄膜的制备实现荧光陶瓷的全光谱照明，通过Al2O3薄膜的制备，增强了荧光薄膜的附着力，增强了荧光陶瓷整体的耐磨性，抗腐蚀性，并且进一步增强了热稳定性。
