Photoactive and Ultrastable Silicon/Boron Doped Diamond Photoanodes Enable Longstanding Photoinduced Electrochemiluminescence

open access: yesAdvanced Optical Materials, EarlyView.
This study introduces a highly durable n‐Si/BDD photoanode for photoinduced electrochemiluminescence that entirely circumvents conventional interfacial passivation. By delivering a stable photovoltage under near‐infrared irradiation, the heterojunction facilitates low‐potential optical upconversion.
