Luminescent Properties of Glasses Based on Lithium Tetraborate Doped with Sm3+ and Gd3+

Glasses based on lithium tetraborate obtained by solid-phase synthesis and doped with earth elements Sm3 +, Gd3 + have been investigated. The absorption and photoluminescence spectra were measured. The phenomenon of transfer of excitation energy from gadolinium ions to samarium ions is considered. A diagram of the energy levels of Sm3+ and Gd3+ in the studied glasses is proposed.
