Abstract
This study explores an advanced luminescence protocol, aiming to reveal recombination mechanisms behind stimulated luminescence in MgB4O7: Dy, Na (MBO), and BeO: Cr, Mg, Sn (BeOR). The two-stage protocol integrates elements from prior methodologies. In the initial phase, materials undergo precise annealing at varying temperatures, followed by Thermoluminescence (TL) measurements. The second stage involves repeating annealing procedures with a single high dose. Materials exhibit localized peaks within dosimetric regions. The analysis reveals MBO's two distinct excited states, valuable for understanding recombination mechanisms and potential transitions. While BeOR undergoes a complete transition, MBO shows indications of a similar transformation. The confirmed presence of two distinct excited states within MBO establishes a fundamental premise. Validation includes peak shape methods (PSM), initial rise (IR), and prompt isothermal decay (PID). This approach enhances the understanding of stimulated luminescence phenomena, providing insights into trapping parameters and transitions between states in the studied materials.
