Abstract
The crystalline state of terbium-containing yttria is one of the important candidates for uses to ultraviolet- and electron-excited green phosphors. To increase the intensity of green emission, structural design of the polycrystalline Y2O3:Tb was carried out using a chemical-vapor-deposition technique operated under atmospheric pressure. The green luminescence intensity was strongly dependent upon the concentration of Tb. The intensity of the photoluminescence at 542 nm obtained from 〈100〉 oriented Y2O3:Tb whiskers was higher than that obtained from the uniform Y2O3:Tb polycrystalline film with random orientation.
