AbstractThe GeO2-PbO-Bi2O3-SrF2 (GePbBiSr) glass systems doped with Eu3 +, Tb3 +, Tm3 + and triply-doped with Eu3 +/Tb3 +/Tm3 + 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 RE3 + ions hosts. RE3 + ions can be excited by single UV light wavelength (355/378/395 nm) and simultaneously emit red, green and blue light originating from Eu3 +, Tb3 + and Tm3 + transitions. Emission color changes from bluish-purple for 355 nm excitation to white when irradiated with 378 nm and 395 nm. The GePbBiSr glass triply-doped by Eu3 +/Tb3 +/Tm3 + ions could be a potential candidate for white LED applications.
