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).

The proposed concept can be extended to cover any part of the solar spectrum by using a set of dye molecules with overlapping absorption spectra acting as an extremely broadband antenna system, connected to suitable upconverters. Near-imfrared quantum yield measurements of colloidal NaYF4: Yb,Er nanoparticles in which the upconversion occurs.

To address these limitations, recently, enormous research input has been directed towards the development of NIR dye-sensitized UCNPs as they offer prominent advantages including a broader absorption range and enhanced upconversion efficiency. However, the practical lignt of the most efficient known upconversion materials at moderate light intensities is limited by their extremely weak and narrowband near-infrared absorption.

Jump to main content. About the author Dr. Such unique properties are at the core of the widespread applications of UCNPs in solar cells, security inks, mear-infrared, clinical applications and bioimaging both in vitro and in vivofor instance. Here, we introduce the dye-sensitizer of an upconversion material where an organic near-infrared dye is used as an antenna for the? 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.
