Description

This package provides a sophisticated computational framework for modeling charge carrier dynamics in materials subjected to optical and thermal stimulation. It implements advanced physical models for optically stimulated luminescence (OSL) and radiation dosimetry applications.

Key Features

Multi-Process Simulation

• Photostimulation Analysis: Wavelength-dependent photoionization cross-section calculations with Gaussian light source simulation
• Irradiation Modeling: Trap filling dynamics during radiation exposure with competition effects
• Thermal Washing: Thermal release of trapped charges using the TTOR (Two-Trap One-Recombination center) model
• Optical Washing: Combined thermal–optical stimulation effects analysis

Advanced Physical Models

• Extended TTOR model with three eV electron traps (user selected)
• Temperature-dependent detrapping via Arrhenius equation
• Wavelength-dependent photoionization probabilities
• Charge neutrality verification and validation

Flexible Input System

Supports:

• Single values: 470
• Ranges: 300,400,25
• Multiple values: 300-350-400

Output

• Three-panel diagnostic plots per simulation
• Publication-quality PNG images (300 DPI)
• Tab-delimited text files (Origin / Excel compatible)
• Pandas DataFrames
• Automatic Google Colab download support

Scientific Applications

• Radiation dosimetry and OSL dosimeter characterization
• Material science defect studies
