A highly efficient multifunctional nanoplatform for simultaneous upconversion luminescence (UCL) imaging and photodynamic therapy has been developed on the basis of selective energy transfer from multicolor luminescent NaYF(4):Yb(3+),Er(3+) nanoparticles (UCNPs) to photosensitizers (PS). Different popular approaches based electrostatic or hydrophobic interactions, over 100 photosensitizing molecules were covalently bonded every 20 nm UCNP, which significantly strengthened UCNP-PS linkage...
Abstract Water oxidation is a critical process for electrochemical water splitting due to its inherent sluggish kinetics. In spite of the high catalytic activities noble metal‐based electrocatalysts oxidation, their cost, rare reserves, and low stabilities drive researchers exploit efficient but low‐cost electrocatalysts. Ultrathin 2D nanomaterials are considered oxygen evolution reaction (OER) in splitting. Herein, facile strategy proposed fabricate FeNi layered double hydroxide (FeNi‐LDH)...
The novel nanostructures have been designed to balance the robustness of upconversion emission and FRET efficiency for image-guided photodynamic therapy under triggering 808 nm light.
It is generally accepted that a lanthanide ions based upconversion material follows an activator low doping strategy (normally <3 mol%), because of the restriction harmful concentration quenching effect. Here, we demonstrate this limitation can be broken in nanostructures. Simply by using inert shell coating strategy, effect for (Er3+) could eliminated and highly efficient luminescence realized fully doped nanostructure, e.g. NaErF4@NaYF4. More importantly, novel nanostructure achieves some...
Photoswitchable materials are important in broad applications. Recently appeared inorganic photoswitchable upconversion nanoparticles (PUCNPs) become a competitive candidate to surmount the widespread issue of organic counterparts —photobleaching. However, current PUCNPs follow solely Yb3+/Nd3+ cosensitizing mode, which results complex multilayer doping patterns and imperfectness switching UV–blue region. In this work, we have adopted new strategy construct Nd3+ free...
Upconversion emission dynamics have long been believed to be determined by the activator and its interaction with neighboring sensitizers. Herein this assumption is, however, shown invalid for nanostructures. We demonstrate that excitation energy migration greatly affects upconversion dynamics. "Dopant ions' spatial separation" nanostructures are designed as model systems intimate link between random nature of time behavior is unraveled theoretical modelling confirmed spectroscopically....

Dye sensitization is becoming a new dimension to highly improve the upconversion luminescence (UCL) of lanthanide-doped nanoparticles (UCNPs). However, there still lack general understanding dye-UCNPs interactions, especially confused large mismatch between inputs and outputs. By taking dye-sensitized NaYF4:Yb/Er@NaYF4:Nd UCNPs as model system, we not only revealed in-depth energy-dissipative process for UCL but also confirmed first ever experimental observation energy back transfer (EBT) in...
