Paper Abstract

40P2O5-20Al2O3-(30-x)Na2O-10BaO-xEr2O3 (PANB) glasses with different Er3+ concentrations were fabricated by the traditional melt quenching method and their spectroscopic properties were investigated. Glass thermal stability is investigated by differential scanning calorimetry (DSC) (Tx-Tg=138°C) which indicates a better recrystallization performance than that of fluorophosphates glass and fluorotellurite glass. The derived Judd-Ofelt intensity parameters of Er3+ doped PANB glass (Ω2=18.8, Ω4=15.9, Ω6=5.38(×10-20cm2 )) indicate higher asymmetry and stronger covalent environment when compared with Er3+ doped tellurite, fluoride and fluorotellurite glasses. Compared with Er3+ transitions in other glass hosts, large stimulated emission cross-section and broad full wave at half maximum (FWHM) were found to be 4.58×10-20cm2 and 60 nm centered at ∼1550 nm, respectively. It implies a potential material for infrared lasers and amplifiers.
