Photoluminescent and Electroluminescent Properties of Cd sub 0.95 Mn sub 0.05 Se Electrodes.
Abstract
Photoluminescence (PL) and electroluminescence (EL) can be used to characterize electric fields in semiconductor electrodes through their influence on electron-hole pair recombination. Solid solutions of II-VI compounds such as n-CdS and n-CdSe have provided a useful family of tunable band gap materials for such studies. We have extended these studies to emissive electrodes derived from a solid solution of MnSe and CdSe. In this paper we report that PL from N-Cd0.95Mn0.05Se electrodes used in photolectrochemical cells (PEC's) can be used to map the electric field in these solids, and that EL obtained from the electrodes originates, on average, nearer the semiconductor-electrolyte interface than PL.
