“…In LiF:Mg,Cu,P, the residual signal and high temperature peaks also can be reduced by increasing the sintering temperature (Tang et al, 1999). The optimum sintering temperature for LiF:Mg,Cu,Si was found to be 830 C (Tang et al, 2013;Kim et al, 2004). The sintering temperature for standard LiF:Mg,Cu,P (Tang et al, 1999) was much lower than that for LiF:Mg,Cu,Si, which should be related to Si in LiF:Mg,Cu,Si and might be related to the high level of Mg (Tang et al, 2013).…”

“…The height of the high-temperature peaks for LiF:Mg,Cu,Si is not only lower than that for GR-200A, but also lower than that for HMCP. Why the height of the high-temperature peaks for LiF:Mg,Cu,Si is lower than that for HMCP is partly because of very high sintering temperature for LiF:Mg,Cu,Si (Tang et al, 2013;Kim et al, 2004). In LiF:Mg,Cu,P, the residual signal and high temperature peaks also can be reduced by increasing the sintering temperature (Tang et al, 1999).…”

“…In the last ten years, the LiF:Mg,Cu,Na,Si material has attracted the researchers' attention. The effect of the dopant concentrations on the TL glow curve in LiF:Mg,Cu,Na,Si phosphor was investigated [15,16]. The role of the dopants in TL mechanism for LiF:Mg,Cu,Na,Si phosphor was studied by analysing the TL emission spectra [17][18][19].…”

Abstract. In the current work the glow curves for LiF:Mg,Cu,Na,Si thermoluminescent material were measured and analyzed by using a function approximating to the well-known Randall-Wilkins first-order expression. The influence of different heating rates on thermoluminescent glow-peak maximum temperature, peak height and integrated area of the glow peak was investigated for LiF:Mg,Cu,Na,Si phosphor. The results show that the glow-peak temperature, peak height and glow peak area increase with increasing heating rate, while the full width at half maximum of glow peak almost keeps constant in the range of heating rates studied.

“…There are a number of commercially available thermoluminescent dosimeters (TLD) for this purpose known by different trade names, the most popular being LiF : Mg, Ti (TLD-100), LiF : Mg, Cu, P (TLD-700H), CaSO 4 : Dy (TLD-900), CaF 2 : Dy (TLD-200), Al 2 O 3 (TLD-500), and so on [17,18]. But efforts are still being made to improve the TL characteristics of these phosphors by preparing them using different methods and giving different heat treatments or by doping with different impurities [19][20][21][22] or by developing some new ones [23][24][25].…”

K3Na(SO4)2 : Eu nanocrystalline powder was synthesized by the chemical co-precipitation method. The x-ray diffraction pattern of the nanomaterials shows a hexagonal structure for its crystals having grain size of ∼28 nm. Transmission electron microscopy revealed that the K3Na(SO4)2 : Eu nanoparticles are single crystals with almost a uniform shape and size. Thermoluminescence (TL) was taken after irradiating the samples at various exposures of γ-rays from a 60Co source. A prominent TL glow peak is observed at 423 K along with three small peaks/shoulders at around 382, 460 and 509 K. The observed TL sensitivity of the prepared nanocrystalline powder is around 4 times more than that of LiF : Mg,Ti (TLD-100) phosphor. The 423 K peak of the nanomaterial phosphor eventually shows a near linear response with exposures increasing up to very high values (as high as 70 kGy), where all the other TLD phosphors saturate. This property along with its other desired properties such as high sensitivity, relatively simple glow curve structure and low fading makes the nanocrystalline phosphor a suitable dosimeter to estimate low as well as high exposures of γ-rays. TL analysis using the glow curve deconvolution technique was also done for determining different trapping parameters.
