BROADBAND DYE-SENSITIZED UPCONVERSION OF NEAR-INFRARED LIGHT PDF

Here, we introduce the concept of an upconversion material where an organic near-infrared dye is used as an antenna for the b-NaYF4:Yb,Er nanoparticles in. Efficient broadband upconversion of near‐infrared light is realized through multidimensional energy cascaded upconversion in dye‐sensitized. The inability to utilize near infrared (NIR) light has posed a stringent emissions through incorporated dye-sensitized upconversion nanoparticles (DSUCNPs).

However, the practical applicability of the most efficient known upconversion materials at moderate light intensities is limited by their extremely weak and narrowband near-infrared absorption.

Such unique properties are at the core of the widespread applications of UCNPs in solar cells, security inks, biosensing, clinical applications and bioimaging both in vitro and in vivofor instance. The authors have particularly focused on achieving strong NIR-I emission rather than visible upconversion emission as the latter suffers from limitations of shallow tissue penetration depth, which again is not beneficiary for biological applications.
