Summary: This study investigates the influence of solvent and gas environments on the photoluminescence (PL) properties of lanthanide-doped nanocrystals, and explains the changes in PL spectrum and excited-state lifetimes using energy transfer mediated by molecular vibrations. EVET-mediated quenching holds promise for probing the local chemical environment of nanocrystals dispersed in a liquid or exposed to gaseous molecules.

Summary: The photoluminescence of lanthanide-doped nanocrystals can be quenched by energy transfer to nearby molecular vibrations, which is often undesired but can provide information about molecular vibrations in the local environment. This study investigates the influence of solvent and gas environments on the photoluminescence properties of NaYF4:Er3+,Yb3+ upconversion nanocrystals and relates the changes to quenching by electronic-to-vibrational energy transfer. The results suggest that EVET-mediated quenching can be used as a mechanism to probe the local chemical environment in liquid and gas-phase systems.

Summary: This study presents high-resolution absorption and laser-excited fluorescence studies of KY3F10:Er3+ core-only nanoparticles. A total of 49 crystal-field energy levels distributed among 13 multiplets of the Er3+ ion have been deduced for the C4v point group symmetry center in this material. A parametrized, single-electron crystal-field calculation demonstrates an excellent approximation to the experimental data, with optimized crystal fit parameters comparable to the bulk KY3F10:Er3+ crystal.

Summary: Research on upconversion emissions from lanthanide-doped nanocrystals has attracted significant interest in various fields. Rational modulation of upconversion emissions is essential for meeting specific application requirements. Local structure engineering offers a feasible method for tuning upconversion emissions by adjusting emission intensity, selectivity, wavelength shift, and lifetime through control of local structure.

Summary: The mechanisms of nucleation and growth of europium-doped terbium phosphate nanocrystals under acidic conditions were studied using kinetic isotope effects and luminescence intensity monitoring. Delayed nucleation was observed, which was attributed to the formation of pre-nucleation clusters or polymers of the lanthanide and phosphate ions. The results suggest that the pre-nucleation and nanocrystal growth processes have similar chemical properties.

Summary: In this study, the decay time of the H-3(4) state in Yb3+, Tm3+-doped nanoparticles was introduced for improved nanothermometry in biological applications. The strong 800 nm upconversion emission in the first biological transparency window was utilized for lifetime nanothermometry, marking the first use of a single upconversion band for this purpose.

Summary: This paper investigates the influence of non-lanthanide dopant insertion on the structural attributes of UC crystals through synchrotron-based X-ray probing, revealing that Li+ doping leads to variations in crystal structures without predictable effects on UCL intensity behavior. The study highlights the existence of local lattice disorder reflected in lattice strain, which correlates with changes in UCL intensity regardless of activator ions, indicating a perturbation of local symmetry field connected with local disorder not always manifested through average structural attributes like lattice parameters.

Summary: In this study, a general strategy based on the simultaneous design of electronic and optical states is proposed to achieve dynamically switchable single-mode lasing. By integrating reversely designed nanocrystals with size-mismatched coupled microcavities, a crosstalk-free violet-to-red single-mode behavior is experimentally demonstrated. This research provides insights into the reverse design of luminescent materials and opens up new opportunities for frontier applications.

Summary: The development of top-down hybrid rattle-shaped thermometers based on Hollow Periodic Mesoporous Organosilica (HPMO) and inorganic hosts is presented. These hybrid materials can efficiently emit lanthanide-based nanothermometers for potential use in future in vivo applications. Additionally, they have been shown to be non-toxic and can be used as a vehicle for drug delivery and release, potentially leading to a new generation of theranostic nanomaterials.

Summary: Despite years of research, the coupling between metallic and upconverting nanoparticles (UCNPs) is still not well-understood. This study reveals that surface plasmon polaritons (SPPs) in silver nanowires can impact the upconverted luminescence (UCL) intensity, dynamics, and spectral properties of UCNPs.
