Study of highly stable electrochemiluminescence from [Ru(bpy)3]2+/dicyclohexylamine and its application in visualizing sebaceous fingerprint

Abstract

For the first time, we report a novel and highly stable visual electrochemiluminescence emission from the [Ru(bpy)₃]²⁺/dicyclohexylamine system at physiological pH conditions, with a quantum efficiency (Φ_ECL) of 95.5%. Furthermore, we have successfully demonstrated the simple and rapid smartphone-based ECL mapping of sebaceous fingerprints via a non-destructive mode.
