The ultimate goal is to develop an efficient photon upconversion platform that can drastically improve solar cells, photodetectors, photocatalysis, and bioimaging, chiefly by facilitating the use of NIR photons. This will be the first study on plasmon enhanced molecular TTA-based photon upconversion. There is no previouswork on this topic because since most experiments are conducted in solution, diffusion makes it difficult to quantify any enhancement when Brownian motion is constantly changing the distance of the light absorber or emitter from the plasmonic structure. This proposal avoids the problems associated with diffusion by considering only photon upconversion in thin films. Here, the focus is on the synthesis and characterization of optical frequency nanoantenna geometries, and their effects on photon upconversion in the solid state. A Bruker AVANCE Neo 400 NMR spectrometer was acquired. This NMR spectrometer provides the breadth and ease of use of a routine spectrometer while affording unprecedented sensitivity. It facilitates the characterization of hybrid materials, various combinations of nanocrystals, small molecules or polymers.
