Abstract

In this paper through the fusion method we prepare the sample based on 45PbF₂45GeO₂10WO₃ host glass co-doped Yb³⁺/Er³⁺ rare-earth ions. During the preparation glass annealing temperature is 380° and constant temperature time lasts over 4 hours. Through the V-prism we find that refractive index of host glass is 1.517 and that of this sample is approximately 1.65. At the same tiem we observe the transmissivity by using the UV-visible-IR spectrography during the wavelength range from 0.35 to 2.5μm. The transmissivity of host glass is beyond 73 percent. That of the sample is beyond 50 percent and there are characteristic absorption peaks of rare-earth ions. Moreover we observe the excitation spectrum by using Japanese Hitachi F4500 fluorescent photometer whose pump light is 980nm semiconductor laser. There are a strong emission peak at 550nm and a weak peak at 680nm. Finally through the discussion and analyiss we point out new reserach and development of upconversion luminescence glass.
