Eu{sup 3+}/Tb{sup 3+} singly and co-doped Y{sub 3}Al{sub 5}O{sub 12} (YAG) phosphors were synthesized by the modified sol-gel method. The prepared phosphors were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscope (FE-SEM) and luminescence analysis. Cubic YAG formation was confirmed by XRD. A strong characteristic emission from Eu{sup 3+} and Tb{sup 3+} ions was identified and the influence of doping concentration was studied. Energy transfer mechanism was observed from Tb{sup 3+} to Eu{sup 3+} ions in the co-doped phosphor. The CIE co-ordinates cover orange-red to green with increasing the Tb{sup 3+}ion concentration.
