Three new homobinuclear nanosized supramolecular copper coordination polymers are hydrothermally synthesized by self-assembly reaction of L-tyrosine (Tyr), terephthalic acid (H2bdc), pyromellitic acid (H4btec) and benzimidazole (Hbzim) with copper chloride salt to generate with formula ]n 1. The accuracy of the CGCD method is dependent upon both the model expressions used and the intrinsic trapping parameters of the TL material.

Results revealed the benefits of comparing kinetic parameters determined from different model expressions and those obtained using experimental TL evaluation methods to assess the reliability of deconvo-lution results. The performance of the computerized glow curve deconvolution (CGCD) method was also tested using simulated glow curves.

The consistency of kinetic parameters determined using different model expressions was assessed using measured TL glow curve of CaF2:Dy. We provide a comprehensive, flexible, convenient, and openly accessible program to analyze TL glow curves according to different models and expressions. This study provides a unified presentation of thermoluminescence (TL) glow-curve deconvolution within the framework of the open source R package "tgcd", according to various analytical expressions that describe first-, second-, general-, and mixed-order kinetics as well as the recently developed semi-analytical expressions that derive from the one trap-one recombination center (OTOR) model that utilizes the Lambert W function or the Wright Omega function. Using this concept, the Dose Response Curves (DRCs) of dosimetric TL peaks of BaSO 4 have been constructed. These peaks are located at 102.2☑.8, 117.3☑.0, 127.0☑.3, 134.7☑.2, 144.4☑.5, 153.1☑.3, 164.4☑.1, 173.3☑.2, 182.3☑.5, 193.8☑.8 and 201.0☑.6 K, respectively which is in agreement with the recent finding on structure of glow curves of H 2O ice.We also demonstrate that the software is a convenient tool not only to locate but also to integrate satellite peaks that may be used for dosimetry/dating. The fourth derivative plots of a set of twelve glow curves of D 2O ice excited with a dose 7.6 kGy (e-beam 2.2 MeV) and recorded with linear heating rate of 0.05Ks -1 show clearly the existence of as many as eleven TL peaks in the range 77-250 K. This is shown by considering the glow curves of NaCl recorded with various heating rates. The "PeakFit" is a simple but convenient, powerful tool in extracting the two most important intrinsic trapping parameters namely, the activation energy (E) and frequency factor (s) of TL peaks of complex glow curves, has been demonstrated. Some applications of the commercial software "PeakFit v.4.12" in thermoluminescence (TL) studies have been reported.
