Low temperature thermoluminescence behaviour of Y2O3 nanoparticles

分享 导出
摘要 Y2O3 nanoparticles were investigated using low temperature thermoluminescence(TL)experiments.TL glow curve recorded at constant heating rate of 0.4 K/s exhibits seven peaks around 19,62,91,115,162,196 and 215 K.Activation energies and characteristics of traps responsible for observed curves were revealed under the light of results of initial rise analyses and Tmax-Tstop experimental methods.Analyses of TL curves obtained at different stopping temperatures resulted in presence of one quasi-continuously distributed trap with activation energies increasing from 18 to 24 meV and six single trapping centers at49,117,315,409,651 and 740 meV.Activation energies of all revealed centers were reported in the present paper.Structural characterization of Y2O3 nanoparticles was accomplished using X-ray diffraction and scanning electron microscopy measurements.
