Investigation of Modification Effect of B2O3 Component on Optical Spectroscopy of Er3+ Doped Tellurite Glasses

摘要: Abstract To investigate the modification effect of B 2 O 3 component on tellurite glass, a series glasses with composition xB -(80- x )TeO -10ZnO-10Na ( = 0, 10, 20, 30, 40, 50, 60, 70, 80) and an additional amount 0.5% Er (in molar) were prepared. The refractive index, absorption edge host, J-O parameters +, fluorescent decay time, bandwidth, quantum efficiency for 4 I 13/2 → 15/2 transition obtained theoretically experimentally. These results indicated that introduction modified performance glass. For example, increasing content , index host decreases from 1.9 to 1.5, shifted toward blue regime, intensity parameter Ω 6 changed 1.08 × 10- 20 (for pure glass) 1.98 cm borate glass), bandwidth increased, decreased.
