Summary: This study developed a new nanotheranostic agent that enables dual modal imaging and photothermal therapy. By synthesizing core-shell-shell upconversion nanoparticles and coating them with an antimony shell, the researchers achieved good biocompatibility and photothermal therapeutic effect. The nanotheranostic agent showed efficient upconversion luminescence imaging under 808 nm laser irradiation and demonstrated potential for magnetic resonance imaging.

Summary: This study evaluates the designed virtual core-shell NP models for UCNPs and proposes new designs of UCNPs as FRET donors. The luminescence kinetics of UCNP donors during RET and new disparity measurements are discussed. These studies help understand the energy transfer and migration between lanthanide ion dopants in UCNPs and how the core-shell architecture affects their performance as FRET donors to organic acceptor dyes.

Summary: Functional colloidal nanoparticles capable of converting between various energy types are widely used in applications such as cancer therapy. This study evaluated the light-to-heat conversion properties of 17 different nanoheaters and ranked them qualitatively. The results showed that considering only the light-to-heat conversion efficiency is not enough, and the absorption coefficient should also be taken into account.

Summary: In this study, we systematically compared and quantitatively analyzed the photothermal conversion efficiency of materials doped with rare earth ions. We also investigated the influence of different matrix materials on the efficiency. The research findings suggest that neodymium ions exhibit the highest internal and external photothermal conversion efficiency, and NdVO4 shows promise as a host material for future applications.

Summary: This study demonstrated that temperature-driven irreversible structural phase transformations in Eu3+ activated LaPO4, La0.5Y0.5PO4, and YPO4 nanocrystals can be utilized for thermal history measurements in the temperature range of 200°C-1000°C. The changes in Eu3+ local surroundings due to temperature increase modified the intensity and emission spectra, and the intensity ratio of Eu3+ 5D0 -> 7F2 to 5D0 -> 7F1 emissions served as a highly-sensitive indicator of the highest temperature experienced by the nanocrystals. The proposed ratiometric readout strategy enhanced the accuracy of thermal history analysis.

Summary: This research investigates the effect of temperature on sensitized photon avalanche (PA) emission in Yb3+ and Pr3+ co-doped NaYF4 nanoparticles. The results show significant variations in PA nonlinearity, gain, and threshold under temperature changes. Moreover, a new thermometric parameter, PA pump power threshold, with high relative sensitivities, is proposed.

Summary: By carefully designing the composition and architecture of nanomaterials, modern functional nanomaterials can possess enhanced properties and multifunctional capabilities. This study presents YPO4:Cr3+ nanoparticles and evaluates their photothermal performance based on the concentration of Cr3+ ions. The results show that despite a low light-to-heat conversion efficiency of only 15%, CrPO4 exhibits a significantly higher temperature increase compared to NaNdF4 nanoparticles when optically excited, indicating its high application potential. An experiment involving dynamic photo-thermo-polymerization of MMA for 3D printing demonstrates the practicality of these photothermal agents.

Summary: Materials capable of emitting UV radiation under NIR excitation are highly desirable for various applications. This study investigates the size, structure, and luminescence properties of tetragonal LiY(Gd)F-4 nanocrystals doped with different concentrations of Gd3+ ions. The results demonstrate that low concentrations of Gd3+ ions can modify the size and up-conversion luminescence, while excess doping leads to the appearance of foreign phases and a significant decrease in luminescence intensity. The intensity and kinetics of Gd3+ up-converted UV emission are also analyzed. These findings provide a foundation for the development of optimized materials and applications based on LiYF4 nanocrystals.

Summary: The time-domain all-optical information processing capabilities of photon-avalanching nanoparticles at room temperature have been discovered. These nanoparticles exhibit properties similar to neuronal synapses and can perform feature extraction, pattern recognition, and data processing without the need for machine-learning algorithms. The high nonlinearity and residual energy storage of these nanoparticles enable all-optical data processing and storage on photonic chips.

Summary: Luminescence thermometry is a powerful technique that allows for non-invasive temperature monitoring through light. This study presents the use of isolated single up-converting NaYF4:Er3+/Yb3+ nanocrystals as functional temperature indicators for monitoring the temperature of a single silver nanowire. The results demonstrate the precise determination of temperature distribution in the nanowire's surroundings using individual nanocrystals, which is an important step for nanoscale luminescence thermometry applications.
