Tta upconversion review coordination

WebHowever, many TTA-UC studies are limited to energy upconversion within the visible spectrum range. For photovoltaic cells with a higher band gap, which harvest the higher energy spectrum (UV region), an efficient Vis-to-UV upconversion is preferred. The Vis-to-UV TTA-UC system was first introduced in 2006. http://alpha.chem.umb.edu/chemistry/ch612/documents/CastellanoCoordChemrev.pdf
