AN ELECTROCHEMILUMINESCENCE TECHNIQUE FOR ELECTRODE SURFACE STUDIES AND THE VISUALIZATION OF FARADAIC PROCESSES - PROCEDURE, EQUIPMENT, ANDEXPERIMENTAL STUDIES

An electrochemiluminescence (ECL) technique and associated equipment w ere developed, and experimental studies of electrode surface structure performed in solutions during electrolysis. The configuration and het erogeneity of surfaces and the presence of thin transparent dielectric films on surfaces can be revealed with a resolution of about 1 mum by analysis of the resulting ECL surface images. Changes in electrochemi cal reaction rates on different surface sections could be quantitative ly estimated by photoelectrical recording of the ECL intensity along s elected directions of the electrode image. It was pointed out that wit h this technique it should be possible to visualize faradaic processes occurring at the interface, determine the heterogeneity of interfaces in nondestructive testing, etc.
