Synthesis and Characterization of Eu, Tb doped Y2SiO5 Phosphors

The structural and the optical properties of Terbium and Europium doped yttrium silicate phosphor particles were analyzed. The samples were prepared through solid state reaction method and investigated in a doping concentration of Tb(2%) and Eu(1.5%). The prepared phosphors are characterized using X-ray diffraction (XRD), SEM.FTIR and PL emission of Y2SiO5 phosphor doped with Tb(2%) and Eu(1.5%) was studied. The observed PL emission is at 380 nm followed by the emissions with good intensity at 487, 545, 586, 613 and 622nm. The present phosphor may be a good candidate for LED
