Mohanty, V. Rai, Y. Dwivedi, S. Rai] TeO2-PbO glasses doped/codoped with Er3+/Er3+-Yb3+ ions have been fabricated by melting and quenching method. Efficient frequency upconversion emissions spanning from blue to red regions corresponding to the 2H11/2, 4S3/2→4I15/2 and 4F9/2→4I15/2 transitions, respectively, upon excitation with 976 nm diode laser radiation have been observed. The variations observed in the intensity of whole upconversion emission spectra due to the presence of the Yb3+ ions are reported and discussed in detail. Springer-Verlag, 2011 Mohanty D.
