摘要：
In this paper we present the calculated electronic structures and associated properties of a green phosphor, Gd2O2S : Tb3+ and compare with experiment. Calculations are performed using the spin polarized relativistic version of the self-consistent field XY scattered wave molecular orbital cluster method and the augmented spherical wave band structure supercell method. The band structures and the associated energy level diagrams of this phosphor will be used to study the luminescence mechanism of Gd2O2S : Tb3+ and to interpret its optical, photoconductivity and XPS spectra.
