The Spectroscopic Properties of Er3+-doped TeO2-Nb2O5 Glasses with High Mechanical Strength Performance
Er3+-doped(100-x) TeO2-xNb2O5(x=5,10,15,20 mol%) niobic tellurite glasses were synthesized,and their density,refractive index,glass transition temperature,crystallization temperature,Vickers microhardness,absorption spectra,fluorescence spectra and the lifetimes of Er3+: 4I13/2 level were measured. The Judd-Ofelt strength parameters Ωt(t=2,4,6) and the stimulated emission cross-section (σemi) were calculated by Judd-Ofelt theory and McCumber theory,respectively. The compositional dependence of optical parameters of Er3+ in glass samples wase investigated. The properties of Er3+-doped niobic tellurite glasses were compared with that of the typical 75TeO2-20ZnO-5Na2O(TZN) tellurite glass in aspect of thermal,mechanical,spectroscopic properties and amplification merit.
