Synthesis and characterization of Eu3+ doped SrY2O4 phosphor

The present paper reports that TL glow curve and kinetic parameter of Eu3+ doped SrY2O4 phosphor irradiated by beta source. Sample was prepared by solid state preparation method. Sample was characterized by XRD analysis and particle size was calculated by Debye-Scherrer formula. The sample was irradiated with Sr-90 beta source giving a dose of 10Gy and the heating rate used for TL measurements are 6.7 C/s. The samples display good TL peaks at 106 degrees C, 225 degrees C and 382 degrees C. The corresponding kinetic parameters are calculated. The photoluminescence excitation spectrum at 247 and 364 nm monitored with 400 nm excitation and the corresponding emission peaks at 590,612 and 624 nm are reported. (C) 2013 Elsevier GmbH.
