Abstract
The GeO2-PbO-Bi2O3-SrF2 (GePbBiSr) glass systems doped with Eu3Â +, Tb3Â +, Tm3Â + and triply-doped with Eu3Â +/Tb3Â +/Tm3Â + ions were successfully synthesized. Their structural and luminescent properties have been investigated with various techniques. Obtained results indicate that these glass systems are suitable materials for the RE3Â + ions hosts. RE3Â + ions can be excited by single UV light wavelength (355/378/395Â nm) and simultaneously emit red, green and blue light originating from Eu3Â +, Tb3Â + and Tm3Â + transitions. Emission color changes from bluish-purple for 355Â nm excitation to white when irradiated with 378Â nm and 395Â nm. The GePbBiSr glass triply-doped by Eu3Â +/Tb3Â +/Tm3Â + ions could be a potential candidate for white LED applications.
