摘要

测定了在氧气和氢气中熔融的Li2B4O7玻璃中Cr、Eu和Dy离子的吸收和发射光谱，并进行了价态和激发态分析。结果表明，Cr6+离子的存在受到起始混合物的组成和熔化气氛的限制，这些离子以Cr6+O4络合物的形式出现。

Optical properties of Li2B4O7 glasses doped with rare-earth and transition-metal ions

Absorption and emission spectra of Cr, Eu and Dy ions in Li2B4O7 glasses melted in oxygen and hydrogen were measured for valency states and excited states analysis. It was stated that the presence of Cr6+ ion is limited by composition of the starting mixture and atmosphere of the melting and that this ions arises as Cr6+O4 complex.
