This upconverting system typically demands efficient conversion of spin-singlet harvested energy through intersystem crossing to spin-triplet states, accessible only in rare metallic-coordinating macrocycle compounds or heavy-metal-containing semiconductor quantum dots for triplet sensitization. Herein, we describe an organic–inorganic system for NIR-to-visible triplet fusion upconversion, interfacing commonly-seen, non-metallic, infrared dyes (IR806, IR780, indyocynine green, and CarCl) and lanthanide nanocrystal (sodium ytterbium fluoride) as a hybrid molecular sensitizer, which extracts molecular spin-singlet energy to nanocrystal-enriched ytterbium dopants at ~48% efficiency (IR806, photoexciation at 808 nm). Moreover, ytterbium sub-lattice energy migration increases the interaction possibility between the nanocrystal and the freely-diffusing rubrenes in solution, resulting in 24-fold (IR806) to 1740-fold (indocyanine green) upconversion (600 nm) increase, depending on the IR dye type, as compared to the one without ytterbium nanotransducers. Ab initio quantum chemistry calculations identify enhanced spin-orbital coupling in the ytterbium-IR806 complex and high energy transfer rate in the ytterbium-rubrene interaction (1010 s 1). Employing inorganic lanthanide nanocrystals as nanotransducers unleashes the potential use of non-metallic infrared organic dyes for triplet fusion upconversion.]]> Wed 04 May 2022 14:38:56 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000896009 Thu 16 Jun 2022 13:20:53 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000787709 Mon 23 Nov 2020 09:32:04 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000901391 Mon 17 Oct 2022 14:24:14 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000645480 Fri 21 Dec 2018 09:50:26 KRAT ]]>
