The distribution of shallow traps within the sol-gel synthesized ZnO nanoparticles was investigated using thermoluminescence (TL) experiments in the 10-300 K temperature range. TL measurements presented two overlapped peaks around 110 and 155 K. The experimental technique based on radiating the nanoparticles at different temperatures (T-exc.) between 60 and 125 K was carried out to understand the trap distribution characteristics of peaks. It was observed that peak maximum temperature shifted to higher values and activation energy (E-t) increased as irradiating temperature was increased. The E-t vs. T-exc. presented that ZnO nanoparticles have quasi-continuously distributed traps possessing activation energies increasing from 80 to 171 meV.

Trap distribution in AgIn5S8 single crystals: Thermoluminescence study Delice, S.; IŞIK, MEHMET; Hasanlı, Nızamı (2018-03-01) Distribution of shallow trap levels in AgIn5S8 crystals has been investigated by thermoluminescence (TL) measurements performed below room temperature (10-300 K). One broad TL peak centered at 33 K was observed as constant heating rate of 0.2 K/s was employed for measurement. The peak shape analysis showed that the TL curve could consist of several individual overlapping TL peaks or existence of quasi-continuous distributed traps. Therefore, TL experiments were repeated for different stopping temperatures (...
Low temperature thermoluminescence behaviour of Y2O3 nanoparticles Delice, S.; IŞIK, MEHMET; Hasanlı, Nızamı (2019-01-01) 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 T-max-T-stop experimental methods. Analyses of TL curves obtained at different stopping temperatures resulted in presence of one quasi-contin...
Thermoluminescence properties of ZnO nanoparticles in the temperature range 10-300 K IŞIK, MEHMET; YILDIRIM, TACETTİN; Hasanlı, Nızamı (2016-04-01) Low-temperature thermoluminescence (TL) properties of ZnO nanoparticles grown by sol-gel method were investigated in the 10-300 K temperature range. TL glow curve obtained at 0.2 K/s constant heating rate exhibited one broad peak around 83 K. The observed peak was analyzed using curve fitting method to determine the activation energies of trapping center(s) responsible for glow curve. Analyses resulted in the presence of three peaks at 55, 85 and 118 K temperatures with activation energies of 12, 30 and 45 ...
Defect characterization in neodymium doped thallium indium disulfide crystals by thermoluminescence measurements Delice, S.; Hasanlı, Nızamı (2016-10-15) Characteristics of defect centers in neodymium doped TlInS2 single crystals have been investigated in virtue of thermoluminescence measurements carried out at low temperatures (10-300 K) with various heating rates between 0.4 and 1.2 K s(-1). One glow peak was detected with peak maximum temperature of 26 K at a rate of 0.4 K s(-1). The observed glow peak was analyzed using three points and heating rate methods. The analysis results revealed the presence of one trap level with activation energy of 14 meV. Th...
Optically stimulated luminescence characteristics of BeO nanoparticles synthesized by sol-gel method ALTUNAL, VOLKAN; YEĞİNGİL, ZEHRA; TÜKEN, TUNÇ; Depci, T.; ÖZDEMİR, ALİ CAN; Guckan, V.; Nur, N.; Kurt, K.; Bulur, Enver (2018-11-01) Optically Stimulated Luminescence (OSL) properties of the sol-gel synthesized nano-powders of Beryllium Oxide (BeO) were investigated. Luminescence properties of BeO nanoparticles are dependent on the crystal structure, particle size, and morphology and therefore strongly dependent on the way of synthesis, thus the preparation was modified to enhance the OSL signal from the material. Structural, thermal and morphological properties of BeO in nanopowder and pellet forms were studied using X-Ray Diffraction (...
