ABOUT THIS BOOK
This book features detailed worked examples of Python code for the analysis and modeling of luminescence signals. Users can run immediately the Python codes, and modify them for their experimental data and to explore the various luminescence models. The theory and equations behind each subject are summarized, and appropriate references are given from the literature, so that researchers can look up the details of the theory and the relevant experiments. The book and the Python scripts contain comments explaining the structure and the various parts of the code. Researchers can use the Python codes to analyze their own experimental data, and to extract the various parameters describing mathematically the luminescence signals.
HOW THE USE THE PYTHON CODES
The book contains 99 Python scripts, which are self contained and ready to run, and represent new codes written by the author. The codes are organized in folders by chapter in this repository.
The book assumes some basic knowledge of Python, however I believe that it will be useful for both newcomers to Python, as well as to experienced programmers who wish to learn more about the various luminescence phe- nomena.
Experienced programmers will certainly find out that they can improve the Python codes given here, and it is of course possible to make the codes more compact and elegant. However, I chose to provide Python codes which are simple and clear, and which can be easily modified for the purposes of the reader, rather than attempting to create compact codes which may be diffcult to follow. I have kept the number of required external Python pack- ages intentionally at a minimum, so that newcomers can follow the Python codes easily. All figures in this book were produced using the Python codes in the book, so that users know immediately what to expect when they run the codes. Additional drawings for the various luminescence models in the book were drawn using Inkscape, and the book was produced overall using LyX.
The presented codes and models fall within two broad categories, based on delocalized and localized transitions. In delocalized transition models the conduction and/or valence band participate in the luminescence process. By contrast, in the localized type of models the luminescence process does not involve the energy bands, but rather takes place between the ground an/or excited state of the trapped electron/hole, and an energy level of the recom- bination center.
This document introduces general examples of experimental lumines- cence data, and discusses the various experimental techniques for measuring the luminescence signals. These signals include thermoluminescence (TL), Optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), as well as the commonly used experimental modes of continuous wave (CW-OSL or CW-IRSL), linearly modulated (LM-OSL or LM-IRSL), constant heating rate TL, isothermal TL (ITL) and time-resolved (TR). Two chapters are dedicated to the analysis of the dose response of luminescence materials.
I hope you will find the scripts useful and that you will enjoy running and modifying the various files. If you find that some script is not clear or has inaccuracies, kindly let me know at vpagonis@mcdaniel.edu
Enjoy!
