Photoluminescence and XEL in Y2O3:Eu3+ phosphor

Eu-activated Y2O3 phosphors were prepared by combustion synthesis and also by precipitation techniques. Photoluminescence and X-ray excited luminescence of prepared Y2O3:Eu phosphor, under two different techniques were compared and reported in this paper. Y2O3:Eu3+ phosphor were prepared by precipitation technique followed by annealing at 900 °C. It gives cubic nature of the particle that may be more favourable for high lumen output. X-ray excited luminescence of Y2O3:Eu3+ phosphors also reported in this paper.
