Optical study of Yttrium oxide doped with zinc prepared by simple methods

Yttrium oxide nanophosphors doped with zinc were prepared using simple methods like sot-gel and solvothermal with solvents like Ammonium Hydroxide, and Sodium Hydroxide as precipitating reagents. Calcining and grinding are necessary to obtain phosphors in the range of 20-30 nm. The Photoluminescence properties investigation reveals that Yttrium oxide samples doped with zinc show a strong blue-green emission with the strongest peak centered at 500nm under the excitation of 250nm UV light.
