Abstract

The spectral and kinetic characteristics of Er3+ ions in heavily doped BaY1.8Lu0.2F8 mixed crystals have been studied. Absorption and luminescence spectra were recorded for BaY1.8Lu0.2F8 crystals with Er3+ ion concentrations of 20.0 and 30.0 at.%. The kinetic dependences of luminescence decay in the infrared range have also been studied. A model of the level populations of Er3+ ions is constructed on the basis of a three-level scheme for pumping the 4I11/2 state at a wavelength of 970 nm without taking into account up-conversion processes. The gain of BaY1.8Lu0.2F8 crystals with Er3+ ion concentrations of 20.0 and 30.0 at.% is estimated at different pump powers.

研究了重掺杂BaY1.8Lu0.2F8混合晶体中Er3+离子的光谱和动力学特性。记录了Er3+浓度分别为20.0和30.0 at.%时BaY1.8Lu0.2F8晶体的吸收光谱和发光光谱。本文还研究了红外范围内发光衰减的动力学依赖性。在不考虑上转换过程的情况下，基于在970 nm波长处泵送4I11/2态的三能级方案，构建了Er3+离子的能级居群模型。当Er3+离子浓度分别为20.0和30.0 at时，BaY1.8Lu0.2F8晶体的增益。%是在不同的泵功率下估计的。
