Abstract

The novel glasses within composition: 62TeO2-5K2TeO3-20ZnO-10Nb2O5-3PbF2 and 62TeO2-5K2TeO3-20ZnO-10Nb2O5-3PbF2-2Er2O3 in mol% were fabricated by using meltquenching technique. The magnetic properties Viz; Faraday effect and the Verdet constant at wavelength of laser beam (λ = 632 nm) were measured. The prepared sample with doped Er3+ has the highest value of Verdet constant (= 0.104min/G.cm) which depends on the polarizability of Er3+ ions. Moreover, the optical properties of present glass estimated by using UV-Vis-NIR spectroscopy. The oxygen-packed densities, molar volumes, the polarizability of the oxygen molar volume, the linear refractive index (n), third-order nonlinear susceptibility, (3)  , and nonlinear index (n2) of produced glasses were evaluation. It was found that the linear refractive index decreases otherwise the optical energy gap increased with doped Er3+ ions in the glasses network. Also, the Vickers microhardness increase with increasing Er2O3 in the glass matrix. Hence, these glasses may be use in optical isolator with high third-order non-linear susceptibility.

稀土掺杂K2TeO3后TeO2的磁光和力学性能

采用熔淬法制备了62teo2 - 5k2teo3 - 20zno - 10nb2o5 - 3pb2和62teo2 - 5k2teo3 - 20zno - 10nb2o5 - 3pb2 - 2er2o3的新型玻璃。磁性能为;测量了激光束(λ = 632 nm)波长处的法拉第效应和Verdet常数。掺Er3+的样品具有最高的Verdet常数(= 0.104min/G.cm)，这取决于Er3+离子的极化率。此外，利用紫外-可见-近红外光谱技术对该玻璃的光学性能进行了估计。评价了氧填充密度、摩尔体积、氧摩尔体积的极化率、线性折射率(n)、三阶非线性磁化率(3)和非线性折射率(n2)。结果表明，Er3+离子的掺入使线性折射率降低，光学能隙增大。显微硬度随Er2O3含量的增加而增加。因此，这些玻璃可用于具有高三阶非线性磁化率的光隔离器。
