|Abstract:||The production of neodymium glass in the chemical composition of 44.75 B2O3-44.75P2O5- 10Li2SO4 has been reported. An intense up-converted violet colour emission has been observed upon excitation with a yellow light. The violet colour up-conversion process has been explained by an energy level scheme. By correlating the measured fluorescence lifetime results with the absorption data, the quantum efficiency (η=44%) of the optical material has been evaluated from the application of Judd-Ofelt theory.|
