Abstract

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.

Sm3+和Gd3+掺杂四硼酸锂玻璃的发光性能

摘要

已经研究了基于通过固相合成获得并掺杂有地球元素 Sm3+、Gd3+ 的四硼酸锂的玻璃。测量吸收光谱和光致发光光谱。考虑了激发能从钆离子转移到钐离子的现象。提出了所研究玻璃中Sm ³⁺和Gd ³⁺的能级图。
