Quantum Dot-Based Sensitization System for Boosted
Photon Absorption and Enhanced Second Near-Infrared Luminescence of
Lanthanide-Doped Nanoparticle
Posted on 2020-04-09 - 12:33
Efficient
energy transfer is a promising strategy in overcoming
the inherent limits of a narrow band and weak absorption of lanthanide
ions due to the nature of 4f–4f transitions. Herein, we introduce
a nanoparticle-sensitized nanoparticle system where a near-infrared-emitting
quantum dot (QD) is used as a sensitizer with broadband photon absorption
for a lanthanide-doped nanoparticle (LNP) to generate second near-infrared
(NIR-II) emission. The NIR-II luminescence of Er3+-doped
LNP by Ag2S QD sensitization displays an enhancement of
∼17-fold in intensity and ∼10-fold in brightness over
bare LNP because of increased absorptivity and overall broadening
of the absorption spectrum of LNP. Furthermore, a QD-sensitized LNP
system exhibits excellent photostability and is able to improve the
signal-to-noise ratio of tumor NIR-II imaging via in situ cross-linking of QD and LNP. The QD-sensitized
LNP system for luminescence enhancement opens a potential avenue for
efficient energy transfer in complex nanoparticle–nanoparticle
systems.
