Abstract:Besides various bio-applications such as biomedicine, bioassay, photon dynamic treatment, and drug delivery, UCNPs have also been used in other applications. They can be explored as a NIR absorber in solar cells because they can absorb NIR light which has been wasted in traditional solar cells. They can be used as sensitizer in photocatalysis due to the energy transfer from UCNPs to the quantum dots or organic dyes. They are considered as next generation anti-counterfeiting materials due to their unique optica… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
