Luminescence studies of PbO-Bi[sub 2]O[sub 3]-Ga[sub 2]O[sub 3]-B[sub 2]O[sub 3] glasses doped with Yb[sup 3+]∕Er[sup 3+]

Abstract

The effect of Er3+ concentration on red emission in lead bismuth gallium borate glasses codoped with Yb3+ is studied. Optical absorption and luminescence spectra of all the glasses were recorded at room temperature. The results obtained are discussed quantitatively based on the energy transfer between Yb3+ and Er3+.
