摘要：

The 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. (C) 2017 Elsevier B.V. All rights reserved.
