Unconventional bismuth (Bi2O3) glasses containing zinc oxide (ZnO), lead oxide (PbO), and samarium oxide (Sm2O3) were prepared using a melt quenching technique. The glass density was observed to decrease as the Sm2O3 increased, from 6.881 g/cm3 for 1% Sm2O3 to 6.618 g/cm3 for 7% Sm2O3, due to the replacement of lead content density by samarium content density. Optical absorption spectra were recorded and the optical parameters, such as the optical transition, optical electronegativity, refractive index, high frequency dielectric constant, single oscillator energy, and dispersive energy were determined. The optical parameter values were correlated to the ratio of Sm2O3. The Judd–Ofelt (JO) theory was applied to the absorption spectra of the glass to predict the radiative and laser properties. The JO parameters (Ω2, Ω4, Ω6) were found to be Ω4 > Ω2 > Ω6 and related to the glass structure. These glasses were exposed to apply in photonic applications.

利用Judd-Ofelt理论分析of离子对非常规铋玻璃的结构和光学性质的影响

使用熔融淬火技术制备了包含氧化锌(ZnO),氧化铅(PbO)和氧化mar(Sm 2 O 3)的非常规铋(Bi 2 O 3)玻璃。观察玻璃密度为随着钐2 ö 3克/厘米增加,从6.881 3 1%的Sm 2 ö 3至6.618克/厘米3为7%的Sm 2 ö 3,因为sa含量密度代替了铅含量密度。记录光吸收光谱并确定光学参数,例如光学跃迁,光学电负性,折射率,高频介电常数,单振荡器能量和色散能量。光学参数值与Sm 2 O 3的比例相关。Judd-Ofelt(JO)理论应用于玻璃的吸收光谱,以预测辐射和激光特性。的JO参数(Ω 2Ω 4Ω 6)被发现是Ω 4 > Ω 2 > Ω6,与玻璃结构有关。这些玻璃被暴露以用于光子学应用。
