Multi-phase fluorescent ceramic material and preparation method thereof
The invention discloses a multi-phase fluorescent ceramic material and a preparation method thereof. The chemical general formula of the multi-phase fluorescent ceramic material is Al2O3-(Y1xCex)3(Al1-ySiy)5(O1-yNy)12, wherein x is larger than or equal to 0.001 and smaller than or equal to 0.01, and the mass ratio of Al2O3 to (Y1-xCex)3(Al1-ySiy)5(O1-yNy)12 is 0.5-50: 50-99.5. The preparation method comprises the following steps: weighing Al2O3, Y2O3, CeO2 and a-Si3N4 raw material powder according to a mass ratio and a stoichiometric ratio, and adding a sintering aid and a solvent; performingball milling, drying and sieving to obtain mixed powder; performing dry pressing and cold isostatic pressing to obtain a biscuit; and carrying out high-temperature sintering and double-sided polishingto obtain the Al2O3-(Y1-xCex)3(Al1-ySiy)5(O1-yNy)12 multi-phase fluorescent ceramic.
本发明公开了一种复相荧光陶瓷材料及其制备方法。该复相荧光陶瓷材料，其化学通式为Al2O3‑(Y1‑xCex)3(Al1‑ySiy)5(O1‑yNy)12，其中，0.001≤x≤0.01，0
