Fluorescent ceramic chip and preparation method thereof
A 3D printing method is adopted, solid solution of calcium oxide and europium nitrate is achieved in the process that calcium oxide is hydrated and converted into calcium hydroxide, then calcium oxide powder and europium oxide powder which are evenly mixed at the molecular level are obtained through calcination, the obtained powder serves as a raw material, and the fluorescent ceramic chip is prepared through the preparation method. Powder laying and selective sintering of a high-power carbon dioxide laser are controlled through calculator software, the fluorescent ceramic chip emitting green light is prepared, the fluorescent ceramic chip prepared through the method has the temperature resistance of over 2000 DEG C, the fluorescence intensity is high, the quantum yield is high, and ultrathin ceramic chips in various shapes such as an annular shape can be freely formed.
本发明公开了一种荧光陶瓷片及制备方法，采用3D打印的方法并利用氧化钙水合转化为氢氧化钙的过程中实现与硝酸铕的固溶，再经煅烧得到分子级别均匀混合的氧化钙和氧化铕粉末，以得到的粉末为原料，通过计算器软件控制铺粉和高功率二氧化碳激光器选区烧结，制备得到发绿光的荧光陶瓷片，本方法制备得到的荧光陶瓷片具有超过2000℃的耐温能力，荧光强度高，量子产率高，且可以自由成型各种形状，如环形等超薄的陶瓷片。
