Spectral Properties of Doped Glasses of the 35Bi2O3 · 40PbO · 25Ga2O3 Composition Synthesized in a Quartz Crucible

Resumo

A glasslike material of the 35Bi₂O₃ · 40PbO · 25Ga₂O₃ composition is investigated. Quartz glass is used in the synthesis as the crucible material. It is shown that, compared to the platinum crucible, the high-energy transmission cutoff shifts from 650 to 500 nm, which has enabled us to study the upconversion luminescence spectra of the glass of the 35Bi₂O₃ · 40PbO · 25Ga₂O₃ composition doped by Er³⁺ ions in the range 500–700 nm. The upconversion luminescence spectra for the glass doped by Er³⁺ and codoped by Nd³⁺ and Yb³⁺ ions are obtained.
