Abstract Three basic borate glasses were prepared from the systems (BaO–B2O3), (SrO–B2O3) and (Bi2O3–B2O3) together with samples doped with 0.25% CuO from the three systems. Collective characterizations of the optical, FTIR, photoluminescence spectra of the prepared glasses were carried out before and after impinging to gamma irradiation. The results were analysed in relation with the structural building groups and their housing in the glass network. Optical spectra of the alkaline earth borates reveal distinct UV absorption bands due to unavoidable trace iron impurities (Fe3+ ions). While the Bi2O3–B2O3 glass shows an additional near visible band related to absorption of Bi3+ ions. The CuO doped glasses exhibit distinct greenish blue colors imparting an additional very broad visible near IR band in all samples due to octahedrally coordinated Cu2+ ions. FTIR spectra of the two glass systems of (SrO–B2O3) and (BaO–B2O3) glasses display vibrational bands due to both BO4 and BO3 groups, while Bi2O3–B2O3 glass shows the interference of additional vibrational bands due to BiO6 and BiO3 groups. Photoluminescence spectra of the samples exhibited similar excitation and emission peaks for the three CuO-doped glasses. They are assumed to originate from the excitation of (3 d9 4s3d10) transitions in Cu2+ ions. Gamma irradiation caused some changes in all spectral measurements, and upon inclusion CuO doping no noticeable changes have been identified. Thermal expansion data were analysed and correlated with increasing the amplitude of atomic vibrations, field strength and bond strength of the cations with oxygen.

BaO–B2O3、SrO–B2O3 或 Bi2O3–B2O3 玻璃中铜离子的比较光学、FTIR 和光致发光光谱分析以及伽马辐射的影响

摘要 由系统 (BaO–B2O3)、(SrO–B2O3) 和 (Bi2O3–B2O3) 以及从三个系统中掺杂 0.25% CuO 的样品制备了三种基本硼酸盐玻璃。在受到伽马辐射之前和之后，对制备的玻璃的光学、FTIR、光致发光光谱进行了集体表征。分析结果与结构建筑群及其在玻璃网络中的住房有关。由于不可避免的痕量铁杂质（Fe3+ 离子），碱土金属硼酸盐的光谱显示出明显的紫外吸收带。而 Bi2O3–B2O3 玻璃显示出与 Bi3+ 离子吸收相关的附加近可见波段。由于八面体配位的 Cu2+ 离子，CuO 掺杂玻璃表现出明显的蓝绿色，在所有样品中赋予额外的非常宽的可见近红外波段。(SrO–B2O3) 和 (BaO–B2O3) 玻璃的两种玻璃系统的 FTIR 光谱显示出由于 BO4 和 BO3 基团引起​​的振动带，而 Bi2O3–B2O3 玻璃显示出由于 BiO6 和 BiO3 基团引起​​的额外振动带的干扰。样品的光致发光光谱对三种掺杂 CuO 的玻璃表现出相似的激发和发射峰。假定它们源自 Cu2+ 离子中 (3 d9 4s3d10) 跃迁的激发。伽马辐射在所有光谱测量中引起了一些变化，并且在包含 CuO 掺杂后没有发现明显的变化。
