In the paper, the methods of obtaining and studying of glasses in the NbO₂F-BaF₂-InF₃ and NbO₂F-BaF₂-InF₃-ErF₃ systems are presented. The effect of indium trifluoride and doping with erbium trifluoride on the thermal characteristics and crystallization of glasses is discussed. The networks of glasses in the systems based on NbO₂F are formed by the NbO_nF_n polyhedra connected by the oxygen bridges. Addition of InF₃ into the system leads to formation of InF₆ polyhedra which are embedded into the oxyfluoroniobate networks. A contribution of the erbium fluorescence to the inelastic light scattering spectra of the NbO₂F-BaF₂-InF₃-ErF₃ system was revealed. An assumption of indium luminescence in the examined glasses was made.

本文介绍了在NbO ₂ F-BaF ₂ -InF ₃和NbO ₂ F-BaF ₂ -InF ₃ -ErF ₃系统中获得和研究玻璃的方法。讨论了三氟化铟和三氟化掺杂对玻璃热学性质和结晶的影响。在基于NbO ₂ F的系统中，玻璃网络是由通过氧桥连接的NbO _n F _n多面体形成的。在系统中添加InF ₃会导致形成InF ₆嵌入氟代铌酸网络中的多面体。揭示了fluorescence荧光对NbO ₂ F-BaF ₂ -InF ₃ -ErF ₃系统的非弹性光散射光谱的贡献。假设检查玻璃中的铟发光。
