Description
Summary:•Experimental methods for synthesis and characterization of Eu3+ doped YBO3 phosphor.•Characterization by XRD, FEGSEM, HRTEM, FTIR study for Eu3+ doped YBO3 phosphor.•Photoluminescence study and thermoluminescence study of prepared phosphor.•CIE coordinates for spectrophotometric distribution.•Evaluation of kinetic parameter by peak shape method for thermoluminescence study. The present paper reports the synthesis, photoluminescence (PL) and thermoluminescence (TL) studies of Eu3+ doped YBO3 phosphor. The samples were prepared by the conventional solid state reaction method with different concentrations of Eu3+ ions, which is the most suitable method for large-scale production. The prepared phosphor sample was characterized using X-ray diffraction (XRD), Field Emission Gun Scanning Electron Microscopy (FEGSEM), high resolution transmission electron microscopy (HRTEM), Fourier Transform Infrared Spectroscopy (FTIR), photoluminescence (PL), thermoluminescence (TL) and CIE coordinate techniques. The PL emission was observed in the range 575–650nm range for the YBO3 phosphor doped with Eu3+. Excitation spectrum found at 237, 254 and 395nm. Sharp peaks found around 594, 612 and 628nm with high intensity. From the XRD data, using the Scherer’s formula the calculated average crystallite size of Eu3+ doped YBO3 phosphor is around 201nm. Thermoluminescence study was carried out for the phosphor with UV, beta and gamma irradiation. The present phosphor can act as single host for red–orange light emission in display devices.
