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.
