Summary: The study demonstrates optical temperature sensing based on UCNPs with enhanced sensitivity through dielectric superlensing modulation, resulting in over a 70% increase in thermal sensitivity of the composite film compared to without the superlens. This enhancement is attributed to the modulation of the dielectric superlensing effect on the wave front of upconversion ultraviolet fluorescence.

Summary: Introducing smaller Mg2+ ions to replace Ca2+ site in the BaLaCaSbO6 matrix leads to a significant enhancement in luminescence intensity, red-shift, and luminescence lifetime. These modulations are mainly attributed to the strengthen pressure on the local structure, superior lattice rigidity, and suppression of non-radiative transition after the substitution of smaller Mg2+. The effective lifetime-based luminescence thermometry is achieved due to thermal quenching behavior of Mn4+ ions in the matrix.

Summary: A series of Yb3+- and Er3+-doped Ca3Sc2Si3O12 (CSS) upconversion (UC) phosphors were synthesized by the sol-gel combustion method to develop novel luminescent materials for optical temperature measurement. The addition of Yb3+ greatly enhanced the emission of Er3+ by effective energy transfer. The prepared CSS:Yb3+,Er3+ phosphors exhibited green and red emissions corresponding to specific transitions of Er3+, and showed excellent temperature-dependent behavior with high sensitivity.

The UCL intensity of the annealed samples surpassed those produced by the solid-state method and is comparable to that from the commercial NaYF4:Yb,Er sample. The temperature-dependent luminescence of the synthesized samples was also studied.

Summary: Rare-earth-doped nanoparticles (RENPs) are promising for biomedical applications, but their interactions with proteins forming a protein corona (PC) can influence their fate in cells. This study focused on investigating the composition of the PC and its impact on cellular uptake for different surface-coated RENPs. Results showed that the stability and composition of the PC varied depending on the surface coating, affecting the internalization of RENPs in cancer cells through endocytic pathways. Understanding these nano-biointeractions is crucial for the future use of RENPs in biomedicine.

Summary: The size and shape of nanoparticles have a significant impact on their photoluminescence quantum yield (PLQY). This study found that the distortion of the crystal lattice in nanoparticles smaller than 20 nm led to an increase in PLQY. Additionally, the shape of nanoparticles within the range of 20-60 nm was found to be particularly relevant for PLQY.

Summary: This paper proposes a multi-scale band-limited illumination profilometry (MS-BLIP) to overcome the limitations of existing techniques in solving spatially isolated 3D objects, large variation in surface reflectance, and flexible working distances with meter-square-level fields of view. MS-BLIP combines dual-level intensity projection, multi-frequency fringe projection, and an iterative method for distortion compensation to accurately discern spatially separated 3D objects with highly varying reflectance. Experimental results of dynamic 3D imaging of a translating engineered box and a rotating vase demonstrate the accuracy and applicability of MS-BLIP. MS-BLIP is also applied to capturing full human-body movements at video rate.
