Summary: This study reports a new nanoplatform for improving the thermal sensitivity of nanothermometry through nonthermally coupled upconversion emissions. By observing the gradual decrease of Er3+ and rapid increase of Tm3+, a significant contrast in intensity ratio and emission colors can be achieved. Introducing Ce3+ further enhances the sensitivity and expands the range of thermochromic color change.

Summary: Materials with tunable emission colors, such as lanthanide doped upconversion nanoparticles (UCNPs), have been studied for their potential applications in full-color display. In this study, a novel experimental design is proposed to achieve trichromatic emission from core-shell-structured UCNPs by manipulating energy migration through a dual-channel pump scheme. This study may contribute to the development of convenient and versatile methods for multicolor tuning and the construction of full-color volumetric display systems with high spatiotemporal resolution.

Summary: Recent discoveries have uncovered the temperature-dependent upconversion luminescence behavior of inert-core/active-shell UCNPs, where both the sensitizer and activator are located near the nanoparticle surface, leading to a stronger luminescence thermal enhancement tendency compared to active-core UCNPs. This thermal enhancement behavior appears to be core-size dependent and is suggested to be attributed to the alleviation of surface quenching induced by lattice thermal expansion, based on the relationship between size-dependent luminescence and lattice expansion coefficient.

Summary: The study explores the upconversion luminescence and thermal sensing properties of Er3+, Yb(3+)co-doped oxysulfide, demonstrating that constructing an active shell with an optimum concentration of sensitizers is an efficient way to enhance luminescent intensities and thermal sensitivity. Increasing the Yb(3+)concentration in the shell activates new quenching pathways of Er3+ -> Yb3+ -> quencher from the core to the shell, impacting luminescent intensity. Overall, this research provides a feasible and versatile method to improve the luminescence and thermal sensing properties of Ln(3+)-based materials.

Summary: In this study, multi-functional multi-layer core-shell structure NaYF4: Ce3+/Eu3+@NaYF4 @NaYF4: Ho3+/Yb3+ nanoparticles (NPs) were prepared. These NPs can be used for high relative sensitivity temperature sensing and multimode optical anti-counterfeiting. The relative sensitivity was further improved by the blocking effect and cross-relaxation, and the NPs showed multimode emissions under multiple excitations, enhancing their application in optical anti-counterfeiting. These NPs have promising applications in biological cell calibration, micro-integrated circuits, etc.

Summary: This study demonstrates the use of upconversion nanoparticles in super-resolution nanoscopy to improve imaging quality and speed. By utilizing a doughnut-shaped scanning excitation beam, high-frequency information can be resolved through the doughnut-emission PSF, while lower-frequency information can be simultaneously collected by the Gaussian-like emission PSF. This approach allows for optimized image quality and achieves a spatial resolution of 40 nm, 1/24th of the excitation wavelength, suggesting the development of nonlinear multi-color emitting probes in super-resolution nanoscopy.

Summary: In this study, a rapid electrochemical immunosensor was developed using custom-formulated graphene inks and aerosol jet printing. The sensor demonstrated lower limits of detection and fast response time compared to most commercial SARS-CoV-2 antigen tests. It utilized a single-step functionalization of graphene electrodes with SARS-CoV-2 polyclonal antibody, eliminating the need for nanoparticle functionalization or secondary antibody or metallic nanoparticle labels. The immunosensor had a wide linear sensing range and did not react with other coexisting influenza viruses.
