Co nanoparticle effects on the thermoluminescent signal induced by UV and gamma radiation in ZrO2 powders

Photoluminescence and thermoluminescence properties of pure and rare‐earth‐doped ZrO2 prepared by Pechini‐type sol–gel

“…The figure shows that the TL dose intensity is sensitive to the type of dopants. The result is in line with the literature that this sensitivity impacts competition between traps and recombination centres during irradiation [33,36,39]. It is clear that the dependencies on irradiation dose are sublinear for all materials except ZrO 2 .…”

“…Several glow peaks for different crystal forms [26][27][28] and irradiations [24,[29][30][31][32] have been reported. The position and parameters of peaks depend strongly on the type of irradiation, such as gamma [33][34][35][36], beta [24], X-ray [37,38], electron [39] and ultraviolet (UV) [33] radiation. The dose-response of some of the peaks was reported to be linear [24,32].…”

“…The TL glow curves of ZrO 2 consist of two broad, prominent peaks and several weaker peaks at higher and lower temperatures [48]. The number and position of the peaks are influenced by the irradiation dose [24], the grain size [26,32,39,44,49], the annealing temperature [24,44,50], the excitation wavelength or type of radiation [33,35,49], the composition of the impurities [26,39,44,51] and the heating rate [39,52]. So far, many studies have been reported on the TL properties of ZrO 2 prepared by different synthesis methods, such as burning in solution and sol-gel.…”

“…It has intense TL glow curve with a higher TL signal. This TL signal can be analysed in relation to given doses studied [9]. This oxidebased material has a major disadvantage i.e., it shows an instant loss of the signal within few minutes after exposure to UV radiation [6,7,9].…”

“…This TL signal can be analysed in relation to given doses studied [9]. This oxidebased material has a major disadvantage i.e., it shows an instant loss of the signal within few minutes after exposure to UV radiation [6,7,9]. To overcome this problem, we are using other ions as impurities during the synthesis process to enhance its TL signal [9,10].…”
