Lens type fluorescent composite ceramic for laser illumination and preparation method thereof
The invention discloses a lens type fluorescent composite ceramic for laser illumination and a preparation method thereof, the lens type fluorescent composite ceramic for laser illumination is composed of a YAG ceramic lens and a fluorescent ceramic block arranged at a central focus in the YAG ceramic lens, the fluorescent ceramic block has a chemical formula (Re1-xCex) 3Al5O12, in the formula, Re is one or more of Y, Lu, Ga, Gd and Tb, and x is more than or equal to 0.0001 and less than or equal to 0.005. The preparation method comprises the following steps: preparing the fluorescent ceramic block by a dry pressing method; the preparation method comprises the following steps: preparing gel casting slurry by taking YAG ceramic lens powder as a raw material, coating a fluorescent ceramic block at a central focus of a YAG ceramic lens by adopting two times of gel casting, drying, discharging glue, sintering, annealing and polishing to obtain the fluorescent composite ceramic. According to the method, the luminous efficiency and the heat dissipation capacity can be effectively improved, the emergent light divergence angle can be flexibly controlled, and the prepared fluorescent composite ceramic can achieve the luminous performance of high lumen efficiency and high brightness and can be suitable for long-term stable illumination in different fields.
