سنتز و مطالعه رفتار گرمالیانی نانو ذرات :Tm,Ce2CaF
Calcium fluoride nanoparticles doped with thulium and cerium were synthesized as a novel nanostructure by using the hydrothermal method. The prepared samples were characterized by X-ray diffraction (XRD) and energy dispersive spectrometer (EDS). The crystallite size of about 36 nm was estimated employing Scherer’s formula. Its shape and size were also observed by scanning electron microscope (...
متن کاملساخت دزیمتر گرماتاب LiF:Mg,Cu,P و بررسی تأثیر ناخالصی مس بر خصوصیات گرماتابی آن
LiF powder having particle size of 50-200 µm doped with Mg, Cu and P impurities was produced using melting method. The whole construction process was conducted in a nitrogen atmosphere. The effect of Cu impurity on the thermoluminescence glow curve was investigated and the appropriate amount of Cu was determined. The TL properties of the fabricated phosphor was compared to commercial LiF:Mg,Cu,...
متن کاملCooling rate effects on the thermoluminescence glow curves of Arkansas quartz
Samples of quartz annealed at high temperatures are known to exhibit thermoluminescence (TL) properties which depend on the rate of cooling of the samples to room temperature. Powder samples of Arkansas quartz were annealed in air at temperatures between 500 and 900 °C and were cooled to room temperature at different cooling rates. The TL of both slowly and fast cooled samples was measured at v...
متن کاملThermoluminescence characteristics and kinetic analysis of copper doped magnesium sulfate in gamma irradiation
MgSO4:Cu phosphor was synthesized by solid state method. Optimum concentration of copper was determined at 0.1 mol%. Thermoluminescence characteristics of MgSO4:Cu was studied following gamma irradiation. A linear dose response was observed in dose range of 1Gy to 500Gy. Reusability of this sample was tested after 10 cycles of gamma irradiation and it revealed that the intensity remains approxi...
متن کاملan improved mixed order model for describing thermoluminescence glow curves
an improved mixed order model is presented to describe the thermolumunescence (tl) glow peaks. in this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken into account. therefore, it is expected that the proposed model will produce more realistic kinetic parameters than that of mixed order model. the tl glow curves generated by the...
