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.

Summary: In this paper, the red-to-green emission ratio of NaYF4:Er3+/Yb3+ phosphors was adjusted through power density, pulse width, and frequency. It was found that the ratio increased with the increase of power density, pulse width, and frequency. The effect of power density on the ratio was not significant due to the combined effect of two-photon up-conversion processes and nonradiative relaxation process H-2(11/2)/S-4(3/2) -> F-4(9/2) (Er3+). The changes in ratio caused by pulse width and frequency were attributed to different non-steady-state up-conversion processes of red and green emissions.

Summary: A targeted high-precision luminescence thermometer was designed using a lead-free double perovskite platform by selecting multiple thermally coupled levels (TCLs) of the Er3+ ion. By choosing different TCLs in a single system platform, more precise temperature resolution can be obtained in different temperature regions from 100 K to almost 880 K. This work provides a quantitative guideline for the development of the next generation of temperature sensor based on trivalent erbium ions.

Summary: This study investigates the effect of Er doping on the structural, morphological, and optical properties of ZnO nanostructures. It is found that Er successfully incorporates into the wurtzite structure of ZnO, while a secondary phase of Er2O3 appears at higher doping concentrations. The band gap of ZnO decreases with increasing Er concentration, and photoluminescence intensity is enhanced with high Er concentration and high excitation wavelength. The research findings provide insights for future studies on ZnO-based optoelectronic applications.

Summary: We performed a first-principles study on the effect of Er concentration and intrinsic defects on Er-doped ZnO. Our results showed that the band gap of Er-doped ZnO decreases with increasing Er concentration, while it increases with the presence of O or Zn vacancies. Moreover, the induced magnetic moments in doped ZnO are attributed to Er 4f electrons. Additionally, the magneto-optoelectronic properties of ZnO can be improved by an optimal concentration of Er as well as with the presence of oxygen vacancies.

Summary: Gas sensors based on mesoporous belt-like In2O3 products derived from a single-step electrospinning method were prepared and their sensing performance was evaluated. The sensor annealed at 550 degrees C showed improved sensing capabilities, with a high response rate and short response and recovery times for methane at a lower operating temperature, as well as good stability, selectivity, and a low detection limit. The enhanced sensing behavior was attributed to the mesoporous structure, small particle size, high surface area, and high concentration of oxygen vacancies in the belt-like In2O3 products.

Summary: In this study, a nanofiber network of La1_ xCexCoO3 was prepared and the X-ray diffraction analysis revealed the appearance of CeO2 with increasing Ce-substitution. The gas sensing measurements showed that the combination of nanofiber morphology and the catalytic effect of Ce resulted in enhanced ethanol sensing performance, especially for the La0.8Ce0.2CoO3 sample. The particle-interconnected nanofiber morphology allowed for greater resistance changes and the Ce-substitution increased the surface oxygen defects, promoting a more advanced gas and surface interaction. This research demonstrates the potential ethanol sensing capabilities induced by Ce-partial substitution on the La-site.

This study focuses on the positive synergistic effects of ZnO/ZnFe2O4 heterostructure, which exhibited the best sensing performance among pure ZnO and ZnFe2O4. The enhanced sensing properties were attributed to the higher concentration of oxygen vacancies at the ZnO/ZnFe2O4 interface and enhanced catalytic activity.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
