摘要：
In the present study, a graphical user interface (GUI) toolkit has been developed to analyze the thermoluminescence (TL) glow -curve and evaluate the trapping parameters using TL expression based on the one -trap onerecombination model. The basic idea of the deconvolution analysis in the developed toolkit is based on performing a sequence of successful fits, where the information provided by each fit is used by the next fit until the deconvolution of the entire glow curve approaches an optimum solution. The starting values and ranges of the fitting parameters can be controlled and adjusted to improve the deconvolution analysis of complex structure glow curves. The designed toolkit is also supported by the background -subtraction option to improve the analysis at low irradiation dose levels. The expanded uncertainty at the 95 % confidence level of the fitted trapping parameters is also provided. All the evaluations performed using the designed toolkit are allowed to be extracted into an Excel spreadsheet. The TL-SDA toolkit can be freely downloaded from: TLSDA_v1 - File ExchangeMATLAB Central (https://www.mathworks.com/matlabcentral/fileexchange/154136-tlsda_v1-1)
