Effect of dysprosium concentration on thermoluminescence behavior of ZrO2:Eu3+ phosphor

This work describes the change in thermoluminescence (TL) behavior of ZrO2:Eu3+ nanoparticles due to the dysprosium co-doping synthesized by using the conventional solid state synthesis method. They were characterized by X-ray diffraction (XRD), FTIR (Fourier transform infrared spectroscopy) and transmission electron microscope (TEM). The XRD result shows a nanocrystalline material with a cubical phase along, while TEM images display particles of spherical shapes of diameters in the 25-35 nm range. We report on the TL glow curves and kinetic parameters, activation energy, order of kinetics, and the frequency factor of europium, dysposium co-doped zirconium (ZrO2:Eu3+, Dy3+) phosphor under UV irradiations, The TL glow curves were recorded for different doses of UV exposure at a heating rate of 5 degrees C/s. The kinetic parameters activation energy E, the order of kinetics b, and the frequency factor S of synthesized phosphor of ZrO2:Eu3+, Dy3+ have been calculated by using a peak shape method.
