Abstract
In this communication, we have studied the preparation, optical absorption, and visible upconversion characteristics of this ion on excitation with green (532 nm) and red (797 nm) laser excitation sources in lead tellurite glass samples. Radiative parameters of various transitions/levels were calculated by applying Judd–Ofelt (J–O) theory. Upconversion measurement shows the generation of UV and blue upconversion emissions at 361, 386, 415 and 451 nm wavelengths using 532 nm excitation. In the same way by using 797 nm excitation intense upconversion emissions extended from blue to red regions in Nd3+ doped lead tellurite glass.
