The ability to control the photon emission from single-molecule quantum emitters is the key toward their implementation in optoelectronics. Here we demonstrate that the emission wavelength of a single copper-phthalocyanine (CuPc) molecule can be reproducibly tuned by atomic-scale manipulations on the surface of an ionic crystal, using a scanning probe light microscope. We explain this by the effect of the local dielectric environment on the molecular emitter.
