Synthesis, structural and optical properties of SrZrO3:Eu3+ phosphor

Eu3+ activated Sr1−xEuxZrO3 (x=0.01−0.04) phosphor with perovskite structure was successfully synthesized by using combustion method. 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 reddish-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.
