Original Abstract

Photo-induced transferred charge (PIQ) and photo-induced luminescence (PIL) measurements involve the creation of electron-hole pairs in the phosphor near one of the phosphor/insulator interfaces, transport of this photo-induced charge across the phosphor, and measurement of the charge transferred across the phosphor layer or the luminescence emitted from the phosphor layer, respectively, as a function of the magnitude of the applied DC voltage. In PIQ/PIL experiments the electron and hole transport may be studied independently by simply changing the polarity of the DC bias. In ZnS:Mn alternating-current thin-film electroluminescence (ACTFEL) devices the hole transport may give rise to impact excitation-induced electroluminescence (EL), holes are approximately half as efficient as electrons in contributing to the transferred charge, and that the efficiency of transport is significantly greater for holes than electrons.
