Title: Enhanced UV and suppressed defect related emission in yttrium doped zinc oxide

Yttrium doped ZnO (YZO) synthesized through conventional solid state reaction method using ZnO and Y{sub 2}O{sub 3} as starting material. The formation of YZO compounds were confirmed by X-ray diffraction and Raman spectroscopy. Photoluminescence measurements revealed an enhanced ultra-violet (UV) and suppressed defect related emission in YZO which is due to reduction in the concentration of the defects related to oxygen interstitials (O{sub i}) and zinc vacancy (V{sub Zn}) of ZnO.
