Increasing the concentration of the ionic liquid and initial metal ion in the aqueous phase can enhance the peak intensity of the hypersensitive transition. The advantages of [P-66614][C16H34PO2] were highlighted by comparing the emission intensity of extracted Eu(III) in different organic phases.

Summary: Thermoluminescent materials and persistent luminescent materials with delayed emission have been widely studied for their potential in optical information storage. In this study, the thermoluminescence mechanism of ternary Ln(NO3)(2)Acac(Phen)(2) complexes (where Ln represents Tb(III), Dy(III), or Eu(III)) was investigated through experimental and theoretical methods. The results showed that the terbium and dysprosium complexes exhibited thermoluminescence properties, while the europium complex did not. The study proposed that the phenanthroline molecules in these complexes act as "chemical" electron traps, allowing for the freezing and storage of the excited state of the complexes. These thermoluminescent materials with "chemical" traps have great potential in optical information storage and anticounterfeiting applications.

Summary: The spectral properties of difluoroboron beta-diketonates in a polystyrene matrix were investigated. A bathochromic shift of the fluorescence bands was observed in the steady-state luminescence spectra during the transition from solutions to polymer films, which is attributed to dye self-absorption. It was demonstrated that using a mask to excite a small portion of the film is a simple and convenient method to prevent the effect of dye self-absorption on the fluorescence spectrum structure.

Summary: Researchers have successfully synthesized wurtzite-phase HgTe nanorods using a two-step cation-exchange strategy. The residual Cu content in the final HgTe nanorods can be tuned by adjusting the solvent concentrations, and the photoluminescence peak position of the nanorods can be controlled by reducing the residual Cu content. Furthermore, field-effect transistors based on the synthesized HgTe nanorods exhibit favorable transport characteristics, and the photodetectors show high responsivity.

Summary: This study investigated the chemosensor properties of Eu(III) carboxylatodibenzoylmethanates as applied to ammonia vapors. The experimental results showed that the luminescence intensity of Eu(III) increased linearly with increasing analyte concentration in the range of 3-300 ppm. The study demonstrated that the luminescent response was reversible and the ammonia detection limit was 3 ppm. Quantum-chemical modeling revealed that the optical effect mechanism involved the formation of a rigid H2O-NH3 structural fragment, which eliminated the quenching effect of high-frequency OH vibrations. The proposed chemosensors exhibited high sensitivity and selectivity, suggesting their potential use in food safety control and environmental monitoring for ammonia sensing applications.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
