Abstract
Luminescent materials composed of Ba9â3m/2TbmY2Si6O24 (m=0.005-0.6) were prepared via a solid-state reaction. The dependence of the luminescent intensity of the Tb3+-doped orthosilicates on the Tb3+ content (m=0.005-0.06) is also investigated. The photoluminescence properties of Tb3+ in Ba9â3m/2TbmY2Si6O24 orthosilicate phosphors were elucidated. Using these phosphors, the desired CIE values including emissions throughout the blue, blue-green, and green regions of the spectra were achieved. Co-doping Ce3+ into the Tb3+-doped host structure enabled a high-energy charge-transfer from Ce3+ to Tb3+; accordingly, the Tb3+-Ce3+-doped green phosphors will be useful for applications involving white-light near-UV light-emitting-diodes.
