| Description |
Opto-impedance characteristics of the long persistent strontium aluminate : Eu2+ phosphor
system have been compared with fluorescent strontium chloro-apatite : Eu2+ phosphor. This
study has shown that optical pumping on the long persistent phosphor sample leads to a type of
charge build-up and subsequent dispersion through a diffusion process occurring on a slow
time scale (∼s) centring on the Dy3+ ion in agreement with a three-level scheme based on Dy3+
related hole-trapping–detrapping mechanism.
