Abstract
Photoluminescence (PL) and electroluminescence (EL) from single-crystal, n-type, Al-doped ZnSe (ZnSe:Al) electrodes have been studied. These samples exhibit both edge emission ( lambda //m//a//x approximately 460 nm) and subbandgap emission when excited at several ultrabandgap wavelengths. The latter PL band is particularly intense, with a measured radiative quantium yield of approximately 10** minus **1 to 10** minus **2; the transition appears to be at least partially self-activated (SA) in origin, based on previously reported PL data. Excited-state communication involving the two emissive states is inferred from time-resolved PL measurements. Stable photoelectrochemical cells (PEC's) can be constructed from n-ZnSe:Al electrodes and aqueous diselenide or ditelluride electrolytes.
