Please avoid GOK, unless you have demonstrated that the peak shifts to lower temperatures with increasing doses. Fitting of a single TL curve with GOK usually does not lead to physically meaningful parameters.

I recommend the work by Sunta et al. on this topic: Sunta, C.M., Ayta, W.E.F., Chubaci, J.F.D. and Watanabe, S., 2005. A critical look at the kinetic models of thermoluminescence - II. Non-first order kinetics. J. Phys. D: Appl. Phys. 38, 95-102.

The criticism is also summarized in our recent manuscript that was just accepted for publication: E. G. Yukihara*, A. C. Coleman, R. H. Biswas, R. Lambert, F. Herman, G. King.“Thermoluminescence Analysis for Particle Temperature Sensing and Thermochronometry: Principles and Fundamental Challenges”. Radiat. Meas., in press(2018).

Salut Mihai!

I did some searching on this a while ago as well and came across two free software: http://www.ifj.edu.pl/ccb/nz63/GlowFit.php , but it works only for first order kinetics and also here: http://physica.gsnu.ac.kr/TLanal/ which works also for general order kinetics.

The first one I tested on TLD-100 and works, but I did not have the time to test the second one.

Have a nice day!

Gosh. This is nothing more than peak fitting for a specific type of spectrum (deconvolution is something entirely different). You could use Origin or Igor Pro. Then, you would also have software to do more than just peak fitting--it would do a broader range of science and engineering analysis on the data you obtain (and a modern UI as well). As a long-time user, I unabashedly recommend Igor Pro and suggest that you drop in at the IgorExchange website to browse the user support.

Dr. Weimer...It's not so easy...unfortunately....

Dear Mihai,

Please be careful. It is not just a software that unfolds spectrums. The deconvolution is a science in its self (said by Yigal Horowitz). I don't recommend to use empirical software that unfolds any spectrum using some Gaussian shape expressions. The TL glow-curve has its own theoretical models and TL expressions. Thus, if you are familiar with using the deconvolution analysis method, I recommend the program of Afouxenidis et al. (2012) for GOK analysis. Otherwise, it would be better to contact someone of those authors or someone else to perform the analysis of your curves.

Afouxenidis, D. Polymers, G.S., Tsirliganis, N.C., Kitis, G., Raidat. Prot. Dosim. 149 (2012) 363-370.

Good Luck

My apologies. The term "peak fitting" is a specific type of curve fitting. The process to analyze TL glow curves is clearly curve fitting, not peak fitting. I can understand the confusion my initial wording caused.

Assuredly, if the curve fitting routine can be written in Excel using a hunt-and-peck optimizer routine (see the cited reference from Afouxenidis), it can be written in a robust (and often more trustworthy) application such as Igor Pro, Origin, MatLab, Mathematica, Maple ... I would not claim it is "that" easy to do in one of these apps; I do claim it is fully possible to do. Indeed, based on the statement ... The [deconvolution

I agree with Dr. Sadek. Deconvolution of a TL glow curve is not that simple task, otherwise you may able to deconvolve TL glow curve but the fitting parameters may not have any physical meaning with the actual TL mechanism. If you use any peak fit software, it will fit the glow curve by some predefined functions (e.g. Gaussian, Poisson etc.). But TL glow peak doesn't follow the Gaussian nature. I am using Origin pro 8 software for deconvolution. However, I have not used the predefined functions those are avaliable in Origin. I have written the Kittis General Order equation in Origin Worksheet. From this I can obtain 1st order, 2nd order and general order peak as required. But I must say that though it is quite successful but a little time consuming.

From my knowledge I like to advise  not to use any predefined peak fit software. Try to simulate the peaks using Kittis General Order equation with the help of Excel or origin worksheet.

Good Luck..!

"with general order kinetics" ? The term "order" is related to single (irreversible) chemical reaction, not kinetics. Regards,
