Er < 3 + >-doped YTaO4 luminescent ceramic material and preparation method thereof
The invention provides an Er < 3 + >-doped YTaO4 luminescent ceramic material and a preparation method thereof. The prepared Er < 3 + >-doped YTaO4 high-temperature luminescent ceramic material has excellent fluorescence characteristics. Under the excitation wavelength of 980 nm, up-conversion luminescence is generated, the fluorescence intensity is firstly increased and then reduced along with the increase of the doping amount of Er < 3 + >, when the doping amount is 2 mol%, the optimal fluorescence intensity can reach 16954 (a.u.), color coordinates are basically not changed, and the luminescence color is not changed, which indicates that Er < 3 + > has good fluorescence intensity and stable monochromaticity. The invention provides a good design idea for the preparation of the rare earth doped yttrium tantalate luminescent ceramic.
本发明提供了一种Er3+掺杂YTaO4发光陶瓷材料及其制备方法，所制备而得的Er3+掺杂YTaO4高温发光陶瓷材料具备优异的荧光特性。在980nm的激发波长下，产生上转换发光，随着Er3+掺杂量的增加其荧光强度先上升后下降，当掺杂量为2mol％时达到最佳，荧光强度可达到16954(a.u.)，并且色坐标基本不发生变化，发光颜色不发生改变，说明Er3+具有良好的荧光强度及稳定的单色性。本发明为稀土掺杂钽酸钇发光陶瓷的制备提供了良好的设计思路。
