Abstract:
Low-energy visible light was converted into heat energy through the excitation of the localized surface plasmon resonance of gold nanospheres excited by upconverted emission based on triplet-triplet annihilation of organic molecules. This system allows easy tuning of absorption/emission wavelengths, which is difficult with conventional photothermal conversion using rare-earth elements.
