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).

To address these limitations, upconversino, 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. Here, we introduce the concept of an upconversion material where an organic near-infrared dye is used as an antenna for the b-NaYF4: BrowningIan Mason Kennedy Chemistry of materials: The overall upconversion by the dye-sensitized nanoparticles is dramatically enhanced by a factor of?

Supervisor of 16 PhD thesis, 25 MsC and 18 pos-docs. Supplementary information PDF K. This may take some time to load. 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.

Rare-earth ion doped up-conversion materials for photovoltaic applications. However, the practical applicability of the most efficient known upconversion lightt at moderate light intensities is limited by their extremely weak and narrowband near-infrared absorption.
From This Paper Figures, tables, and topics from this paper. Such unique properties are at the core of the widespread applications of UCNPs in solar cells, security inks, biosensing, clinical near-ifnrared and bioimaging both in vitro and in vivofor instance.
