Visible Light Emission From Dye Molecular Grains via Infrared Excitation Based on the Nonadiabatic Transition Induced by the Optical Near Field

We observed light emission in the visible wavelength range (lambda = 600-690 nm) from aggregated 4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran (DCM) dye molecule grains excited by infrared light (lambda ex = 805 nm). The domains of visible light emission were localized at the surface...
