Abstract

The multicolor intense visible emission from Er3+ and Tm3+ ions codoped in TeO2PbO glass upon excitation at 1064nm radiation from a nanosecond pulsed Nd:YAG laser has been investigated. The optical parameters of erbium ions codoped in Tm3+TeO2PbO glass by using the Judd–Ofelt theory have been determined from the optical absorption spectra. No upconversion (UC) emission was seen in the singly doped Er3+-doped glass upon excitation at 1064 nm. Through the experiments, it has been found that, in the codoped glass, the UC luminescence from Er3+ (2.0 mol. %) in green and red regions corresponding to the H211/2I415/2, S43/2I415/2, and F49/2I415/2 transitions is strengthened about 40, 60, and 130 fold, respectively, at 2.0 mol. % Tm3+ ion concentration in codoped glass. The observed UC emissions and the enhancement observed in their intensity have been explained on the basis of efficient energy transfer and cross-relaxation energy transfer processes.
