Optical properties of rare earth (Ce) and transition metal (Ti) doped ZrO2 phosphors

Abstract

Abstract Thermoluminescence and Photoluminescence of un-doped as well as Titanium (Ti3+) & Cerium (Ce3+) doped ZrO2 phosphors, prepared via solid-state reaction method. For the characterization of the sample FTIR, XRD, EDAX and FESEM study were done. FTIR confirms the presence of conventional impurities (such as NO3, OH-) present in the prepared sample. Structural characterization technique (XRD) shows the monoclinic formation and reveals the average grain size in the nano region. EDAX study confirms the chemical composition and through FESEM morphological status is studied. For kinetic parameters study themoluminescence studies is carried out and try to correlate the XRD results with thermoluminescence behavior of prepared phosphors. Photoluminescence emission spectra show the blue and green emission band for Ti and Ce doped ZrO2 phosphors respectively.
