Structural and thermoluminescence (TL) properties of Gd-doped ZnO nanoparticles were investigated in the present study. TL glow curves recorded in the 10-300 K range presented three overlapped peaks around 56, 110 and 155 K for undoped ZnO nanoparticles. The Gd-doping to the ZnO nanoparticles resulted in shift of peak maximum temperatures to lower values and decrease of activation energies associated with the observed peaks. Activation energies of trapping centers were also reported. Taking into account the previously reported studies on defect characterization of ZnO compound, revealed centers were associated with interstitial defects. Structural characteristics of the synthesized nanoparticles were investigated by x-ray diffraction and scanning electron microscopy measurements.

Annealing effect on the low temperature thermoluminescence properties of GaSe single crystals Isik, M.; Hadibrata, W.; Hasanlı, Nızamı (Elsevier BV, 2014-10-01) Trapping centers in as-grown GaSe single crystals have been investigated by thermoluminescence (TL) measurements in the temperature range of 30-300 K. The analysis of the observed peaks in TL glow curve to determine the activation energies of the associated centers were accomplished using curve fitting, initial rise and peak shape methods. Activation energies of the revealed four trapping centers obtained from various methods were in good agreement with each other on the energy values of 0.14, 0.18, 0.24 an...
TL and OSL studies on gallium sulfide (GaS) single crystals Isik, M.; YÜKSEL, MEHMET; TOPAKSU, MUSTAFA; Hasanlı, Nızamı (Elsevier BV, 2020-09-01) Gallium sulfide (GaS) single crystals were investigated using thermoluminescence (TL) and optically stimulated luminescence (OSL) measurements. TL experiments performed in the room temperature (RT)-450 °C range presented a glow curve consisting in six single discrete peaks. Analyses of TL glow curve by computerized glow curve deconvolution method showed that the trapping centers responsible for peaks are located at 0.98, 1.09, 1.15, 1.76, 1.87 and 1.90 eV. The order of kinetics found between 1 and 2 indicat...
Thermoluminescence characteristics of Bi 12 SiO 20 single crystals Isik, M.; SARIGÜL, NESLİHAN; Hasanlı, Nızamı (Elsevier BV, 2020-08-01) Trapping center properties of bismuth silicon oxide (Bi12SiO20) single crystals were investigated by thermoluminescence (TL) measurements performed in the 50–400 °C temperature range. Experimental TL curve recorded at heating rate of 1 °C/s presented two overlapped peaks around 279 and 362 °C. The heating rate dependency of TL curve was also studied for heating rates between 1 and 6 °C/s. The measured TL curves were analyzed using curve fitting, initial rise and different heating rate methods. The results o...
Multiphoton core ionization dynamics of polyatomic molecules Toffolı, Danıele; Decleva, Piero (IOP Publishing, 2013-07-28) The two-photon core ionization dynamics of gas-phase methane, carbon monoxide and nitrogen have been studied with a recent implementation of the lowest order perturbation theory in the framework of density functional theory and a multicentric basis set expansion of bound and scattering states. Ionization cross sections and angular asymmetry parameters have been calculated for the case of a single radiation beam and for both linear and circular light polarizations in the fixed nuclei approximation. Expected ...
Electronic, mechanical and lattice dynamical properties of YXB4 (X = Cr, Mn, Fe, and Co) compounds CANDAN, ABDULLAH; SÜRÜCÜ, GÖKHAN; Gencer, Ayşenur (IOP Publishing, 2019-12-01) In this study, the physical such as structural, electronic, anisotropic elastic and lattice dynamic properties of YXB4 (X = Cr, Mn, Fe and Co) compounds have been investigated. The electronic properties including band structure and corresponding partial density of states for YXB4 have been calculated. YFeB4 and YCoB4 compounds are found to have metallic behavior while YCrB4 and YMnB4 have semiconductor behavior. Also, the compounds are found to be as non-magnetic materials. The calculated elastic constants ...
