Abstract

Optical transition between singlet and triplet is observed in phosphorescent platinum octaethylporphyrin (PtOEP), on a graphene substrate. PtOEP on single layer of graphene not only modulates the dominant emission wavelength but also enhances the emission intensity. This result addresses new light-matter interactions of the hybrid structure of graphene and a single molecule.

Keywords: Pt-octaethylporphyrin; graphene; photoluminescence; singlet-triplet transition; wavelength modulation.
