Mechanism of photostimulated luminescence: BaFCl:Eu2+

We propose a new parallel model based on the analysis of photostimulated luminescence (PSL) process and existing theoretical models. While solving this model, the general expression for PSL is gained. BaFCl:Eu²⁺, one of the PSL materials, is prepared and a series of spectra are measured. We compared the theoretical and experimental results in terms of the decay process, the difference between two kinds of color centers and the relationship between irradiation dose and luminescent intensity.
