Trapping parameters for peak XII in LiF TLD-100

Journal of Physics D: Applied Physics, 1983
In the TL glow curve of LiF TLD-100, peak IV appears as a shoulder to peak V. There are few data available on trapping parameters for this peak in the literature. The relative intensities of the two peaks were reversed by annealing the sample at 423K for 23 h before irradiation.

On the mechanism of phototransfer thermoluminescence in LiF TLD-100

Journal of Physics D: Applied Physics, 1988
LiF TLD-100 exposed to 25.8 C kg-1 and then annealed at 350 degrees C for 15 minutes contains defects responsible for the 225 nm optical absorption band and peak XII. Other defects have not been identified in this sample. Consequently, phototransfer thermoluminescence (PTTL) has been assumed to originate from peak XII.

On the order of kinetics for thermoluminescence in LiF (TLD-100)

Journal of Physics D: Applied Physics, 1983
Studies of TL glow curves on powder and single crystals of TLD-100 give essential the same results. Differences in materials are not the source of the discrepancy between the authors' results and those of Kathuria and Sunta (1982). In the authors' results, from isothermal annealing of the TL, they find no evidence for non-first-order kinetics and ...

Thermoluminescence of LiF TLD-100 dosimeter crystals

IEEE Transactions on Nuclear Science, 1974
The unusually complex thermoluminescence obtained from Harshaw dosimeter type TLD-100 LiF crystals has been studied with apparatus for measuring emission intensity simultaneously as a function of both wavelength and sample temperature. A separate signal averaged spectrum is obtained at 5.5 C temperature intervals.

On the trapping centres in LiF TLD-100

Solid State Communications, 1980
Abstract Most of the TL in TLD-100 originates from the defects responsible for the optical absorption bands at 310 and 380 nm. Different models have been suggested for these defects and TL mechanism in TDL-100.

Order of kinetics for thermoluminescence in LiF TLD-100

Journal of Physics D: Applied Physics, 1981
Comments on the result given by Kathuria and Sunta (ibid., vol.12, p.1573, 1979) for the order of kinetics of peak V of the TLD-100 thermoluminescence. Further results are presented to support the view that peak V has constant first-order kinetics.

Thermoluminescence of LiF TLD-100: Glow-curve kinetics

Journal of Applied Physics, 1978
The thermoluminescence kinetics have been determined for the 13 glow peaks contained in the glow curves obtained from LiF TLD-100 after exposure to 60Co irradiations. The glow curves were constructed from measurements made with recently developed equipment for recording emission spectra at closely spaced temperature intervals. In addition, the recorded

On the peculiarities of peak 4 in LiF TLD-100

Radiation Measurements, 1994
Abstract A detailed study of the different glow curves that can be obtained from LiF TLD-100 is presented. This study has been made measuring glow curves after different preparation and readout conditions, and using computerized glow curve analysis to resolve individual glow peaks.

Effect of deep traps on the sensitization in LiF (TLD-100) phosphor

Physica Status Solidi (a), 1980
The effect of residual thermoluminescence (RTL) on sensitization (S/S0) of peak 5 (197°C) and peak 7 (257°C) in LiF (TLD-100) is studied. Intense UV irradiation (253.7 nm) at a temperature of 300°C is found to completely remove the RTL peak 8 (321°C) and RTL peak 10 (415°C) without altering very much the sensitization of peak 5.

The emission spectrum of LiF (TLD-100) at low and high exposures

Physics in Medicine & Biology, 1972
The emission spectrum of LiF (TLD-100) was studied for high and low exposures. The ratio of the thermoluminescence of the high exposure (3.4*104 R) to that of the low exposure (100 R) was the same for all wavelengths. A tendency for the emission spectrum to shift to shorter wavelengths with higher temperature glow peaks was observed.
