Abstract
I n situ photoluminescence measurements were used to explain the behavior of the n-InP/electrolyte junction when iodide-iodine redox couple is added to an acid aqueous medium. Adsorption of iodine atoms on the surface of InP drastically reduces the forward-bias luminescence intensity. Luminescence recovery occurs after a large reverse polarization is able, through a photodissolution, to eliminate the adsorbed iodine atoms.Keywords
