在本工作中探索了掺杂有Ho2O3,Er2O3和Tm2O3的60TeO2-20K2TeO3-10WO3-10Nb2O5(以mol%为单位)玻璃的热和光学性能。热稳定性,折射率n,消光系数k,吸收系数α,和光学带隙的玻璃进行了评价。UV-Vis-NIR吸收光谱,Judd-Ofelt强度参数,光谱质量因子,并计算了发射和吸收截面,以研究Er3+和Tm3+的影响,分别,关于Ho3+离子的谱带性质。结果表明,最大发射截面约为8×10-21cm2,半峰全宽(FWHM)的值,品质因数(σe×FWHM),还报道了Ho3+的增益系数:5I7→5I8。FWHM×σe的值为1200×10-28cm3,显示出比早期研究结果更大的增益特性。对于2μm中红外固态激光器,被检查的眼镜可能是一种很好的宿主材料。
The thermal and optical properties of 60TeO2-20K2TeO3-10WO3-10Nb2O5 (in mol%) glasses doped with Ho2O3, Er2O3, and Tm2O3 were explored in the present work. The thermal stability, refractive index n, extinction coefficient k, absorption coefficient α, and optical band gap of the glasses were evaluated. The UV-Vis-NIR absorption spectra, the Judd-Ofelt intensity parameter, the spectroscopic quality factor, and the emission and absorption cross-sections were calculated to investigate the effects of Er3+ and Tm3+, respectively, on the band spectroscopic properties of Ho3+ ions. The results showed that the maximum emission cross-section was approximately 8×10-21 cm2, and the values of the full width at half maximum (FWHM), quality factor (σe×FWHM), and gain coefficient of Ho3+: 5I7→5I8 were also reported. The value of the FWHM×σe was 1200×10-28 cm3, which showed greater gain characteristics than earlier study results. For 2 μm mid-infrared solid-state lasers, the glasses that were examined might be a good host material.
