In this paper, thermoluminescence (TL) properties of TlInS2:Nd single crystals were modeled using an interactive model (one trap and one kind of recombination center). The simulated work presented here was based on the experiment conducted by Delice et al. The thermoluminescence glow curve of TlInS2:Nd single crystals has been characterized by one main peak at 26 K, which confirm the presence of one active electron trap level in the forbidden band of this material. The model used in this work is similar to other models cited previously in the literature. The calculated glow curve was in good agreement with the experimental one. Our numerical results show also that the thermoluminescence intensity increases with the increase of the dose rate (D). In the selected dose level range; the thermoluminescence response is linear and no saturation can be observed. (C) 2017 Elsevier GmbH. All rights reserved.

Time-domain mapping of electromagnetic ray movement inside anisotropic spherical resonator Biber, A; Golick, A; Tomak, Mehmet (2002-09-01) This paper presents the analytical proof of "Time-Domain Mapping Method" for the spherical resonator made up of uniaxial crystal. In this way, the main types of caustics inside the spherical resonator made up of uniaxial crystal, which were investigated numerically before, are confirmed analytically. It is engraved that the problem of the ray flow inside the spherical resonator can be reduced to the problem of the ray flow inside metal cavity shaped as spheroid.
Determination of Trapping Parameters of Tl2In2S3Se Layered Single Crystal by Thermoluminescence Güler, Işıkhan; Hasanlı, Nızamı (2018-04-01) Thermoluminescence (TL) measurements are performed to evaluate the trap states in Tl2In2S3Se layered single crystals. TL experiments are conducted with varying temperature from 10 to 300 K and warming rates from 0.2 to 1.0 K s(-1). From the analysis of both initial rise and curve fitting methods, the activation energy of the traps is obtained as 23 meV. The Chen's method is also used to find activation energy. By means of this technique, the activation energy of the TL glow curve is calculated as 25 meV. Fr...
Strain gradient crystal plasticity: thermodynamics and implementation Yalçınkaya, Tuncay (Springer, 2016-01-01) This chapter studies the thermodynamical consistency and the finite element implementation aspects of a rate-dependent nonlocal (strain gradient) crystal plasticity model, which is used to address the modeling of the size-dependent behavior of polycrystalline metallic materials. The possibilities and required updates for the simulation of dislocation microstructure evolution, grain boundary-dislocation interaction mechanisms, and localization leading to necking and fracture phenomena are shortly discussed a...
Defect characterization of Ga4Se3S layered single crystals by thermoluminescence IŞIK, MEHMET; Delice, S.; Hasanlı, Nızamı (2016-04-01) Trapping centres in undoped Ga4Se3S single crystals grown by Bridgman method were characterized for the first time by thermoluminescence (TL) measurements carried out in the low-temperature range of 15-300 K. After illuminating the sample with blue light (similar to 470 nm) at 15 K, TL glow curve exhibited one peak around 74 K when measured with a heating rate of 0.4 K/s. The results of the various analysis methods were in good agreement about the presence of one trapping centre with an activation energy of...
Temperature influence on the dipalmitoylphosphatidylcholyne - Model membranes studied by FTIR Korkmaz, F.; Severcan, Feride; Aflori, M.; Dorohoi, D. O. (2008-06-01) Lyotropic liquid crystals are realized from certain concentration of amphiphilic molecules, such as phospholipids, in water. The specific interactions in which water is involved are very important for model-membrane stability. Dipalmitoylphosphatidylcholyne (DPPC) model membranes have been studied by FTIR technique at different temperatures in the spectral range {2500 - 4000} cm(-1). A Gaussian deconvolution has been performed in order to study the water behaviour from the point of view of hydrogen-bond for...
