Raman scattering in glassy Li2B4O7 doped with Er2O3

Abstract

We study Raman scattering spectra for glassy lithium tetraborate with different concentrations of doping erbium ions. Most of the vibrational modes found for the activated Li 2 B 4 O 7 :Er 2 O 3 glasses in the medium-scale range are caused by mixed and normal modes of compound boron-oxygen, erbium-oxygen and lithiumoxygen structural complexes.

Structure and chemical durability improvement of alkali silicate glass by zirconium dioxide and erbium oxide addition

“…The addition of rare earth oxides in the glass structure were found to be effective ways to modify various glass properties [20][21][22][23]. The fundamental function of rare earth oxides in glass is modifier since the behavior of rare earth oxides is like other modifier oxides [15,[24][25][26][27][28]. However, rare earth ions have higher field strength than alkali or alkaline earth ions, which the cations tend to be easily incorporated in the glass network at non-bridging oxygen region and produce tighter structures [15,[29][30][31].…”

“…Исследованию колебательных спектров Li 2 B 4 O 7 посвящен ряд работ [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], большинство из которых связано с изучением фононных спектров монокристаллов ТБЛ. Что касается стекловидных боратов на основе Li 2 B 4 O 7 , то данные об их колебательных спектрах крайне ограничены [6,7,14,[19][20][21].…”
