Upconverted emission-driven photothermal conversion with gold nanospheres based on triplet–triplet annihilation

Author affiliations

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.
