The structure, morphology and optical properties of the material were characterized by X-ray diffraction, scanning electron microscopy and fluorescence spectrometry. The XRD results indicated that crystals of SrZrO3：Eu3＋belongs to tetragonal perovskite system. The phosphor could be effectively excited by UV light and the emission spectra results indicated that red-dish-orange luminescence of SrZrO3：Eu3＋due to magnetic dipole transition 5D0→7F1 at 593 nm was dominant. Thus, the prepared phosphor showed remarkable luminescent properties which find applications in field emission display （FED） and plasma display panel （PDP） devices.展开更多
