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 (lambdaex = 805 nm). The domains of visible light emission were localized at the surface and edges of the dye grains, where the optical near field was strengthened. The emitted visible light...
We report that nanophotonic polishing of a silica substrate using a nonadiabatic photochemical reaction drastically reduced the average surface roughness, Ra, and the dispersion of Ra.
We applied nonadiabatic near-field photochemical reaction to the photolithography. The optical near field with the steep spatial gradient of optical power activates the unique photochemical reaction and enables nanometric patterning even by using visible light
We report that a nonresonant optical near field can dramatically influence and regulate the growth of zinc nanoparticles during photochemical vapor deposition. A single 15-nm dot was fabricated in a highly controlled manner.
