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.

If the material has been adapted instead of reproduced from the original RSC publication “Reproduced from” can be substituted with “Adapted from”. Back to tab navigation Download options Please wait 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.

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. Users should refer to the original published version of the material for the full abstract.

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.
