Summary: A responsive fluorescent polyaminoamide nanogel (NANO-PAMAM) was synthesized via a water-based reaction, and then it was covalently linked with doxorubicin to form a ratiometric nanosensor for temperature and pH sensing. The biocompatibility of the nanogel and nanosensor was confirmed by MTT assay.

Summary: A series of Ln-MOFs and codoped Ln-MOFs were synthesized. The luminescent colors of the codoped Ln-MOFs can be controlled and tunable, with gradually changing emission colors. The Tb3+-to-Eu3+ energy transfer in the codoped Ln-MOFs was investigated theoretically, and the efficiency was found to exceed 49%. Additionally, a ratiometric luminescent thermometer was designed using a codoped Ln-MOF, allowing for temperature measurement over a wide range.

Summary: This study reports the synthesis and tunable emission of Sb3+-Ln(3+)-codoped Cs2NaYCl6 single crystals, which exhibit bright white-light emission with high photoluminescence quantum yield. Energy transfer from Sb3+-induced self-trapped excitons to Ln(3+) ions is revealed through spectral analysis. Temperature-dependent photoluminescence spectra demonstrate the potential of this material in ratiometric optical thermometry.

Summary: This study involves the preparation and comprehensive analysis of Dy3+-doped Ca5(PO4)2SiO4 phosphors as non-contact optical temperature sensors. The phosphors exhibit a strong correlation between the luminescence intensity ratio of Dy3+ ions at 453 nm and 480 nm and temperature, indicating high sensitivity. The synthesized phosphor also shows excellent temperature repetitiveness, highlighting its potential as a ratiometric optical temperature sensor over a wide temperature range.

Summary: Rare earth-doped CeF3 2D nanosheets were successfully synthesized in this study, and their morphology was found to be affected by the amount of water in the solvent and the doping amount of rare earth ions. The CeF3:20% Gd, 30% Tb 2D nanosheets emitted bright green light, but the luminescence color changed to red when the Tb3+ ions were partially replaced by Eu3+ ions. The temperature-dependent luminescence properties of CeF3:20% Gd, 25% Tb, 5% Eu make it a promising ratiometric luminescent thermometer for temperature sensing applications.

Summary: Metal-organic frameworks (MOFs) are multifunctional materials with varying framework architectures depending on the choice of metal ions and ligands. One important property is its luminescent behavior, which can arise from the ligand unit, metal ions, or cavity guest molecules. MOFs can be used to construct ratiometric fluorescence (RF) sensors by modifying the ligand unit and selecting suitable metal ions or guest molecules.

Summary: The concept of optical temperature sensing using band intensity ratio is a highly effective and non-invasive technique. In this study, a dual-center system, SrB4O7:Eu2+/Sm2+ phosphors, was employed as a bifunctional sensor for temperature and pressure. The phosphors showed high sensitivity and pressure dependence, making them promising candidates for optical sensing applications.

Summary: Quantum sensing using optically addressable atomic-scale defects, such as the nitrogen-vacancy (NV) center in diamond, provides new opportunities for highly localized and sensitive characterization of chemical functionality. However, the application of NV centers is hindered by degradation of sensor properties near surfaces, and covalent bonding methods with precise control are needed. This review presents the convergence of diamond surface science and NV-center physics, discussing the advantages of diamond surface properties for NV sensing applications, strategies to mitigate detrimental effects, and emerging applications in single-molecule level chemical surface studies.
