Summary: In this study, a series of dual-emissive phosphors were prepared by doping Tb3+ and Bi3+ ions, resulting in a significant increase in the long persistent luminescence intensity compared to the host material Zn2GeO4. The photoluminescence color was adjusted by trap depth engineering, while the persistent luminescence color remained green, and the photoluminescence color under 365 nm UV excitation turned yellow. The dual-emission phosphors were successfully applied in multi-stimulus anti-counterfeiting and the detection of mucin 1 with a wide linear range and low detection limit.

Summary: We have developed a room-temperature and ultrafast approach for synthesizing highly luminescent Eu-doped CaMoO4 nanoparticles. Firstly, CaMoO4 nanoparticles with a size of 3.9 nm are prepared using a room temperature co-precipitation method. Then, Eu-doped CaMoO4 nanoparticles with a photoluminescence quantum yield of up to 75% are synthesized through a post-cation exchange reaction at room temperature. This facile and room-temperature synthetic strategy allows for the preparation of highly luminescent and extremely small rare earth ion-doped metal oxide nanocrystals.

Summary: The fundamental understanding of the solvation structure of liquid electrolyte (LE) and the behavior of the electrode-electrolyte interface will bring deeper thinking and revolutionary changes to the field of electrochemical energy storage. Small-angle X-ray scattering (SAXS) is an ideal complement to other spectroscopic techniques and offers a unique perspective on clusters or networks in electrolytes. Understanding the solvation structures at different scales lays a solid foundation for the study of macroscopic transport properties of LEs, such as viscosity and ionic conductivity.

Summary: In this study, the formation and evolution of phosphatidylcholine-based liposomes were investigated in real-time using graphene liquid cell-transmission electron microscopy (GLC-TEM). The growth, fusion, and denaturation steps of liposomes were revealed. The study showed that complex lipid aggregates resembling micelles formed initially, which randomly merged and captured water to form small proto-liposomes. The liposomes grew in size until their membrane became convex and free of redundant phospholipids. Liposomes were found to fuse through lipid bilayers docking and the formation of a fusion pore. Denaturation of liposomes involved structural destabilization and membrane deformation followed by the leakage of encapsulated liquid.

Summary: In this study, we reported the liquid-crystalline and luminescent properties of a series of N-annulated perylenes. It was found that the liquid-crystalline properties of these compounds depend on the number and position of hydrogen bonding units and amide linkers in the molecule. Compounds with no hydrogen bonding units in the inner part of the molecule exhibit luminescence vapochromism when exposed to organic solvent vapors.

Summary: The study reveals that the viscosity of water confined in graphene oxide nanochannels shows a non-monotonic variation with the density of hydroxyl groups on the graphene oxide sheets, due to the coupling interactions between water molecules and graphene oxide sheets and their relating momentum dissipation among water molecules within water layers, viscous friction among water layers. The calculated viscosity is consistent with experimental and numerical findings, as well as the Eyring's absolute action theory.

Summary: This article demonstrates the controllable synthesis of low-phonon-energy KPb2X5 (X=Cl, Br) nanoparticles and the ability to tune nanocrystal phonon energies as low as 128 cm(-1). KPb2Cl5 nanoparticles are moisture resistant and can be efficiently doped with lighter lanthanides. The low phonon energies of KPb2X5 nanoparticles promote upconversion luminescence from higher lanthanide excited states and enable highly nonlinear, avalanche-like emission from KPb2Cl5 : Nd3+ nanoparticles. The realization of nanoparticles with tunable, ultra-low phonon energies facilitates the discovery of nanomaterials with phonon-dependent properties, precisely engineered for applications in nanoscale imaging, sensing, luminescence thermometry and energy conversion.

Summary: Lifetime-based luminescence thermometry enables accurate deep-tissue monitoring of temperature changes, but short lifetimes and poor brightness limit its performance. A solution to these limitations is the design and optimization of luminescent nanothermometers co-doped with transition metal and lanthanide ions, which exhibit strong near-infrared emission and long temperature-dependent photoluminescence lifetime. These nanothermometers, combined with a custom-made instrument, allow for obtaining 2D thermal maps for deep-tissue thermal mapping. This study provides foundations for the deployment of lifetime-based thermometry for accurate deep-tissue temperature monitoring.

Summary: We present a hydrothermal synthesis method for ultrasmall Yb3+/Tm3+ co-doped Sr2LaF7 (SLF) upconversion phosphors. By varying the concentrations of Yb3+ (x = 10, 15, 20, and 25 mol%) and Tm3+ (y = 0.75, 1, 2, and 3 mol%), the emissions in the near IR spectral range were analyzed. Structural analysis revealed that Yb3+ and Tm3+ occupy the La3+ sites in the SLF host. The addition of Yb3+/Tm3+ ions significantly affected the lattice constant, particle size, and PL emission properties of the synthesized SLF nanophosphor. The optimal dopant concentrations for upconversion luminescence were found to be 20 mol% Yb3+ and 1 mol% Tm3+ with EDTA as the chelating agent. Strong upconversion emission of Tm3+ ions around 800 nm was achieved under 980 nm light excitation. The study suggests potential applications of ultrasmall Yb3+/Tm3+ co-doped SLF phosphors in fluorescent labels for bioimaging and security.

Summary: By preparing colloidal crystals with random missing scatterers, crystals are created where disorder is embodied as vacancies in an otherwise perfect lattice. In this system, there is a critical defect concentration where light propagation undergoes a transition from a perfect reflector to an enhanced transmission phenomenon. This behavior can be phenomenologically described in terms of Fano-like resonances.

Summary: Photonavalanching nanoparticles (ANPs) with highly nonlinear upconverted emission have great potential for subdiffraction imaging, nanoscale sensing, and optical computing. We use Gd3+-assisted energy migration to tune the emission wavelengths of Tm3+-sensitized ANPs and generate highly nonlinear emission from Eu3+, Tb3+, Ho3+, and Er3+ ions. The upconversion intensities of these spectrally discrete ANPs scale with a nonlinearity factor s = 10-17 under 1064 nm excitation at power densities as low as 7 kW cm(-2). This strategy can be extended to fluorophores adjacent to ANPs, as shown with CdS/CdSe/CdS core/shell/shell quantum dots.

Summary: In recent years, there has been significant interest in infrared emitting luminescent nanothermometers due to their potential for new diagnosis and therapy procedures. However, concerns have been raised regarding their reliability, as tissues can induce spectral distortions even in the commonly used second biological window. In this study, the effectiveness of shifting the operation range of these nanothermometers to the third biological window is demonstrated, showing minimal distortion by tissue and opening the path to reliable luminescence thermometry. Advanced analysis of emission spectra allows for sub-degree thermal uncertainties.

Summary: Near-infrared (NIR) luminescence thermometry is a reliable method for remote thermal sensing and imaging. Lanthanide (Ln(3+))-based nanophosphors are commonly used as NIR nanothermometers, but the combination of Ln(3+) with transition metal (TM) ions can enhance the sensitivity of the thermometric approach. However, there are few examples of luminescence nanothermometers combining both TM and Ln(3+), leaving room for further exploration of these systems.

Summary: Luminescence nanothermometry is a technique that uses luminescence signals from nanosized materials to remotely and minimally invasively measure temperature. However, in a biomedical context, the reliability of temperature measurement is compromised by bias caused by environmental conditions. This study reveals an unexpected source of bias induced by metal ions, which enhances the emission of Ag2S nanothermometers. These findings highlight the need for caution when using luminescence nanothermometry in complex biological environments.
