采用传统的熔融淬冷技术合成了（1 - x）[（TeO 2）70（B 2 O 3）30] - x（Gd 2 O 3）（x = 0.2，0.4，0.6，0.8和1.0 mol%）的玻璃样品。进行X射线衍射（XRD）研究以确认样品的无定形性质。已发现样品的密度随Gd 2 O3含量而变化，而在摩尔体积中观察到相反的趋势。红外光谱分析表明，玻璃网络主要由TeO 3、TeO 4、BO 3和BO 4单元组成。Gd 2 O3的加入改变了玻璃样品的折射率、光学带隙和Urbach能量。通过在室温下用闪光灯法测量样品的热扩散率，研究了所研究玻璃的热性质。
Abstract New glass samples with composition (1 – x)[(TeO2)70(B2O3)30] – x(Gd2O3) with x = 0.2, 0.4, 0.6, 0.8 and 1.0 in mol% have been synthesized by conventional melt-quenching techniques. X-ray diffraction (XRD) studies were performed in order to confirm the amorphous nature of the samples. The density of the samples has been found to vary with the Gd2O3 content, whereas an opposite trend has been observed in the molar volume. The analysis of Fourier Transform Infrared (FT-IR) spectroscopy of the samples showed that the glass network is mainly built of TeO3, TeO4, BO3 and BO4 units. The addition of Gd2O3 changed the refractive index, optical band gap and Urbach energy of the glass samples. The thermal properties of the studied glasses were investigated by measuring the thermal diffusivity of the samples by using photoflash method at room temperature.
