TLDecoxcel
Computational Deconvolution of Simple or Complex Glow Curves
TLDecoxcel is a powerful and user-friendly computational tool for the deconvolution of simple or complex thermoluminescence glow curves, implemented in Microsoft® Excel.
The software enables the computational analysis of curves comprising:
- discrete-energy peaks governed by general-order or mixed-order kinetics,
- continuous trap-energy distribution peaks,
- or a combination of the above,
using established analytical mathematical expressions with minimal user intervention.
TLDecoxcel supports the deconvolution of up to twelve (12) discrete-energy components and twelve (12) continuous-distribution components, enabling the analysis of particularly complex glow curves. The quality of the fit is automatically evaluated using the Figure of Merit (F.O.M.), providing an objective criterion for fit optimisation.
The procedure includes entering experimental intensity-temperature data, defining key parameters such as heating rate and background, and selecting the appropriate kinetic model. Parameter optimisation may be performed manually or using the Excel Solver tool, enabling rapid and efficient minimization of the F.O.M.
TLDecoxcel has been successfully validated using synthetic and experimental glow curves, demonstrating its reliability in calculating kinetic parameters such as trap depth (E), kinetic order, and the frequency factor.
The tool is freely available to the scientific community for research use and non-commercial exploitation. It provides a modern digital resource for studying trap properties and performing dosimetric analysis of thermoluminescent materials.
