The present paper reports the variation of photoluminescence behavior of Y3Al5O12 (YAG) with respect to Eu concentration from 0.5 to 3.0 (mol %). The phosphor was synthesized using the standard solid state reaction technique (SSR). The prepared phosphor materials were characterized using powder X-ray diffractometry [XRD], scanning electron microscopy [SEM], and Photoluminescence [PL] (Emission and Excitation). We have studied the effect of dopants on the photoluminescence YAG phosphor monitoring at 400nm. From the PL emission spectrum as increasing the Eu concentration the luminescence peaks at 592,610 and 631nm are gradually increased which is the fundamental emission of Eu. It is found the YAG: Eu+3 phosphors can act as phosphor in compact fluorescent lamps and these nano phosphors may be good candidates for display devices.
