摘要： 本文对Na2O-B2O3-V2O5玻璃体三元系统中的V4+作了ESR研究.通过ESR测量和分析,得到结论:V4+离子以钒酰离子VO2+形式存在于本样品中,是六配位的八面体结构,并且沿四方对称轴有压缩畸变.本文还对V4+的配位键性质作了讨论.

Abstract: V4+ ESR studies were carried out in the system of sodium boro-vanadate glasses (Na2O-B2O3-V2O5), and V4+ ESR spectra were measured and analysed. It was found that V4+ ions present in the glasses were in the form of vanadyl-type ions VO2+. The structure of the V4+ ions was an octahedral six co-ordination with a tetragonal compression. The bonding properties of V4+ ions were discussed as well.
