Schematic representation of direct (a) and indirect (b) CL. Asterisk (*) indicates the excited product. (c) Schematic showing the CL generation mechanism of a classical luminol-H2O2 system with a blue emission at 425 nm. (d) Schematic showing typical examples of annihilation and coreactant pathways for ECL generation. Asterisk (*) indicates the excited product. (e) Schematic illustration of the molecular orbital for demonstrating the general principle of PL. (f) Jablonski diagram displaying the typical photophysical processes in molecule.
