摘要
Er^3＋-doped Na2O-WO3-TeO2 glass consistent with standard ion-exchange technology has been fabricated and characterized. The measured absorption and emission spectra of the glass were analyzed by the Judd-Ofelt and McCumber theories. The intensity parameters are Ω2 = 7.01×10^-20cm^2, Ω4 = 1.80 × 10^-20 cm^2, Ω6= 1.03 × 10^-20 cm^2. The maximum emission cross-section is 0.91 × 10^-20 cm^2 at 1.533μm, and a broad 1.5μm emission spectrum of 65-nm full width at half-maximum （FWHM） is demonstrated. Glass transition temperature, crystallization onset temperature, density, refractive index are also reported for reference in the design and modelling of the ion-exchange process.
