Scanning tunneling microscopy induced luminescence (STML) is a unique method to locally excite and observe excitons and plasmons in an electroluminescent material, leading to the implementation of a combined exciton-plasmon light source. The light emission from a proof-of-concept buckyball-based system is characterized at the nanometer scale and the relative contributions of light originating from excitons and plasmons can be reproducibly tuned by STM parameters under exclusion of any tip modification. This ability is intimately related to an understanding of intrinsic properties of excitons and plasmons, namely, their formation and decay mechanisms in conjunction with their associated timescales.
