    Abstract:
    Polycrystalline Sr2SnO4 phosphors doped with Tb(3+) were prepared by conventional solid-state reaction method. Materials were characterized by powder XRD and EDS techniques. The luminescence properties of these materials were investigated under UV and VUV excitation. Upon excitation at 272 nm, phosphors exhibited intense emissions at 492 and 543 nm due to (5)D4 → (7)F6 and (5)D4 → (7)F5 transitions of Tb(3+) ions, respectively. Materials also exhibited strong emissions from these transitions under VUV excitation at 147, 173 and 230 nm. Quantitative analysis of the spectra indicated probable applications of these phosphors for PDP and other display devices as green emitting phosphors.
