Phase-Dependent Control of Trap Depth and Persistent Luminescence in Strontium Aluminate Phosphors
Published on: December 5, 2025
Abstract:
The relative delay between excitation and luminescence was measured for a number of common inorganic phosphors using short, high intensity excitation pulses. The delays were found to be much shorter than anticipated; on the basis of low intensity pulsed luminescence measurements and were found to be extremely intensity-dependent. Both the luminescence rise and decay times were found to be intensitydependent as well, with the luminescence pulse waveform tending to approach the exciting pulse at the higher excitation intensities.
