Transmission-type three-layer composite structure fluorescent ceramic for laser illumination and preparation method of transmission-type three-layer composite structure fluorescent ceramic
The invention discloses transmission-type three-layer composite structure fluorescent ceramic for laser illumination and a preparation method of the transmission-type three-layer composite structure fluorescent ceramic. The fluorescent ceramic is of a three-layer composite structure which sequentially comprises a (Re1-xCex) 3Al5O12 yellow-green fluorescent layer, a transparent high-heat-conduction heat dissipation layer and a (A1-yCey) 3 (Al1-zBz) 5O12 red fluorescent layer from top to bottom. The preparation method comprises the following steps: placing the yellow-green fluorescent ceramic obtained by dry pressing at the bottom of a copper mold, pouring a magnesium aluminate spinel melt into the preheated copper mold, placing the red fluorescent ceramic above the melt, cooling to obtain a composite structure material, and placing the composite structure material in a muffle furnace for crystallization treatment to obtain the magnesium aluminate spinel composite material. The composite structure fluorescent ceramic with the yellow-green fluorescent layer, the transparent high-heat-conduction heat-dissipation layer and the red fluorescent layer is obtained. According to the method, different ceramic matrixes can be well connected and compounded, the process is simple, and the cost is low; the obtained transmission-type composite structure fluorescent ceramic can maintain higher luminous intensity at high temperature, and has excellent color rendering property.
本发明公开了一种激光照明用透射式三层复合结构荧光陶瓷及其制备方法，荧光陶瓷为从上往下依次为(Re1‑xCex)3Al5O12黄绿色荧光层、透明高导热散热层、(A1‑yCey)3(Al1‑zBz)5O12红色荧光层的三层复合结构。制备方法：将干压成型获得的黄绿色荧光陶瓷置于铜模底部，再将镁铝尖晶石熔融液倒入预热的铜模内，将红色荧光陶瓷置于熔融液上方，冷却后获得的复合结构材料置于马弗炉中进行晶化处理，即得黄绿色荧光层/透明高导热散热层/红色荧光层的复合结构荧光陶瓷。该方法可实现不同陶瓷基质间良好连接和复合，且工艺简单，成本较低；所得到的透射式复合结构荧光陶瓷在高温下可保持更高的发光强度，并获得优异的显色性。
