Abstract
Transparent and uniform tellurite-phosphate glasses were prepared and the reason why the substitution of NaPO3 for P2O5 can eliminate the coloration of tellurite-phosphate was discussed. The result of TDA indicated that introducing NaPO3 into tellurite glasses can improve thermal stability of glass hosts. The compositional dependence of absorption cross-sections of 4I13/2, 4I11/2 and 2H11/2 level, emission cross-section of 4I13/2 level, host phonon energy, up-conversion and 1.5 μm optical emission intensity as well as and quantum yield for 4I13/2 level in PTEr glasses were investigated too. By analyzing obtained data, authors believe that tellurite-phosphate glasses can be used as potential host material for developing optical amplifiers.
