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.
