Abstract

This study employed solid-state synthesis to develop the green emitting Er-Yb:NaZr(PO), NASICON material. Using Rietveld refinement, the crystallographic variables of the synthesized phosphors were precisely calculated. The upconverting phenomenon was seen with naked eye when exposed to 980 nm laser radiation. The intermediate excited state dependency on the unusual photon number dependence on the green and red emission has been understood using the steady-state rate law equations. Further, the temperature sensing performances with good repeatability were compared with different laser densities, and it was found that the prepared phosphors could be an ideal material for upconverting and temperature sensing applications.

摘要

本研究采用固态合成法制备了绿色发光的Er-Yb:NaZr(PO)4、NASICON材料。利用Rietveld精修法精确计算了合成磷光体的晶体学变量。当暴露于980nm激光辐射时，肉眼可见上转换现象。利用稳态速率定律方程，已了解到中间激发态对绿色和红色发射中异常光子数依赖性的依赖性。此外，还比较了不同激光密度下具有良好重复性的温度传感性能，发现所制备的磷光体可能是用于上转换和温度传感应用的理想材料。
