Abstract:
Photostimulated luminescence from thin-film ZnS : Mn structures was studied. Thin-film electroluminescent structures based on ZnS : Mn as a phosphor and aluminium oxide as an insulator were produced using ALD method. Due to high structure quality it was possible to investigate an effect of light stimulated electroluminescence form such structures using 405 nm m blue laser diode as a light source. Two kinds of light-stimulated luminescence were found: short-term luminance growth, explained by additional charge carriers excitated by laser beam; long-term luminance growth, which is to be explained in further works.
