Electroluminescence Associated with Redox Reactions

Electroluminescence is a process in which light of a certain wavelength is emitted from a semiconductor electrode as a result of electrochemical reactions. The results 

According to Kooij et luminescence is due to hole injection from the 

Kooij et al. described the individual steps involved as follows  

According to them, strong oxidizing agents like H2O2 or S2O8 give very limited luminescence at (XP because the reduction of these two-electron redox couples requires 

The open-circuit photovoltage of silicon electrodes may or may not change with redox potentials depending on the system. When Voc follows the variation with redox potential, the band bending is related to the redox potential Vs = E iox )i for
