Summary: In this study, germanate phosphors Li2MgGeO4:Ln(3+) (Ln = Pr, Tm) were synthesized and their luminescence properties were investigated using spectroscopy. X-ray diffraction analysis showed that ceramic compounds Li2MgGeO4 with Pr3+ and Tm3+ ions crystallized in a monoclinic crystal lattice. The luminescence properties of Pr3+ and Tm3+ ions were examined under different excitation wavelengths. The most intense blue emission band of Tm3+ overlapped well with a broad band near 500 nm, while this effect was not evident for Pr3+ ions. Based on excitation/emission spectra and decay measurements, the germanate ceramics Li2MgGeO4 doped with trivalent rare earth ions can be used as inorganic phosphors emitting orange (Pr3+) or blue (Tm3+) light.

Summary: High quality Gd2O2S-based phosphors with high crystallinity, good dispersibility, and relatively good size uniformity were achieved through optimization of flux type and components. The emission properties of matrix and activated ions were studied in the single-doping system, while the composition and coexcitation wavelength of the co-doping system were designed. Adjustable multicolor emission and energy transfer were realized in the co-doping system, supported by spectral overlap, fluorescence intensity change, and fluorescence lifetime decrease. The co-doping phosphors showed excellent thermal stability, adjustable multicolor emission under electron-beam excitation, and good paramagnetic properties, suggesting their potential as optical-magnetic bifunctional materials in luminescence and bioimaging fields.

Summary: The design of novel drug delivery systems is crucial in disease treatments, and mesoporous silica nanoparticles (MSNs) have shown great promise due to their stability, tunable morphologies/sizes, and loading capability. Functionalization of MSNs with drugs, imaging, and targeting agents is enabled by the presence of surface silanol groups, making them versatile and popular among researchers. Stimuli-responsive silanol conjugates have emerged as an effective way to deliver therapeutic drugs precisely and on-demand, and it is important to understand the role of surface silanols in MSN as a drug delivery platform. This review provides an analytical understanding of surface silanols, their chemistry, identification methods, and their correlation with properties and performance.

Summary: Excessive exposure to UV and HEV light can cause skin damage, and the development of effective shielding agents is crucial. In this study, a nanohybrid material called g-C3N4-mica was developed by incorporating semiconducting g-C3N4 into the interlayer space of mica, which showed excellent UV-HEV absorption properties and no photocatalytic activity. It is believed that g-C3N4-mica can be used as a UV-HEV blocking agent without any photocatalytic effect or phototoxicity.

Summary: Researchers have found that triethyl phosphite (TEP) can modulate the enzyme-mimetic activity of cerium oxide nanoparticles (CeNPs) and its influence depends on the Ce3+/Ce4+ ratio on the CeNPs surface. Interaction between TEP and CeNPs with low Ce3+/Ce4+ ratio decreases the catalase- and oxidase-like activities of the CeNPs, while increasing the SOD-like activity. It was also observed that TEP interaction does not affect the surface regeneration of CeNPs and facilitates the formation of defects on the surface of stoichiometric cerium oxide.
