Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue dedicated to "Optical–Electric–Magnetic Multifunctional Composite Materials". This Special Issue aims to showcase cutting-edge research and innovations in the design, synthesis, characterization, and application of composite materials that integrate optical, electrical, and magnetic functionalities. Such materials hold transformative potential for next-generation technologies, including optoelectronics, energy storage, sensing, and biomedical devices. Topics of interest include, but are not limited to, the following: 

  • Novel material architectures (e.g., hybrid nanostructures, layered composites).
  • Synergistic coupling mechanisms between optical, electric, and magnetic properties.
  • Advanced fabrication techniques (e.g., self-assembly, 3D printing).
  • Theoretical modeling and computational insights into multifunctional behaviors.
  • Applications in photovoltaics, spintronics, smart sensors, and electromagnetic shielding/absorption.

The Mo:BiVO4/FeOOH photoelectrode was synthesized through the deposition of FeOOH onto the surface of the Mo:BiVO4 photoelectrode. The composite photoelectrode demonstrated a photocurrent of 1.8 mA·cm−2, which is three times greater than that observed for pure BiVO4. Furthermore, the glycerol conversion rate was recorded at 79 μmol·cm−2·h−1, approximately double that of pure BiVO4, while the selectivity for glyceraldehyde reached 49%, also about twice that of pure BiVO4. The incorporation of Mo has been shown to enhance the stability of the BiVO4. Additionally, Mo doping improves the efficiency of electron-hole transport and increases the carrier concentration within the BiVO4. This enhancement leads to a greater number of holes participating in the formation of iron oxyhydroxide (FeOOH), thereby stabilizing the FeOOH co-catalyst within the glycerol conversion system. The FeOOH co-catalyst facilitates the adsorption and oxidation of the primary hydroxyl group of glycerol, resulting in the cleavage of the C−H bond to generate a carbon radical (C). The interaction between the carbon radical and the hydroxyl group produces an intermediate, which subsequently dehydrates to form glyceraldehyde (GLAD). Full article

The report of the first room-temperature, ambient-pressure superconductivity in copper-doped lead apatite Pb10−xCux(PO4)6O has attracted lots of attention. However, subsequent studies revealed the presence of numerous impurity phases in the polycrystalline sample, and the sharp superconducting-like transition is not due to a superconducting transition but most likely due to a reduction in resistivity caused by the first-order structural phase transition of Cu2S at around 385 K from the β phase at high temperature to the γ phase at low temperature. Before now, only bulk measurements have been performed on a Pb10−xCux(PO4)6O powder sample, which could be affected by the impurity phases, masking the intrinsic properties of Pb10−xCux(PO4)6O. In this study, 31P and 63/65Cu nuclear magnetic resonance (NMR) measurements have been performed on a Pb10−xCux(PO4)6O powder sample to investigate its physical properties from a microscopic point of view. Our NMR data evidence the non-magnetic insulating nature of Pb10−xCux(PO4)6O without any trace of electron correlation effects. Furthermore, the 63/65Cu NMR results suggest that no copper or very little copper is substituted for Pb in Pb10(PO4)6O prepared by sintering Pb2SO5 and Cu3P. Full article

There is considerable interest in broadband nanomaterials, particularly transparent semiconductor oxides, within both fundamental research and technological applications. Historically, it has been considered that the variation in dopant concentration during the synthesis of semiconductor materials is a crucial factor in activating and/or modulating the optical and structural properties, particularly the bandgap and the parameters of the unit cell, of semiconductor oxides. Recently, tin oxide has emerged as a key material due to its excellent structural properties, optical transparency, and various promising applications in optoelectronics. This study utilized the ultrasonic spray pyrolysis technique to synthesize aluminum-doped tin oxide (ATO) thin films on quartz and polished single-crystal silicon substrates. The impact of varying aluminum doping levels (0, 2, 5, and 10 at. %) on morphology and structural and optical properties was examined. The ATO thin films were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmittance spectroscopy. SEM images demonstrated a slight reduction in the size of ATO nanoparticles as the aluminum doping concentration increased. XRD analysis revealed a tetragonal crystalline structure with the space group P42/mnm, and a shift in the XRD peaks to higher angles was noted with increasing aluminum content, indicating a decrease in the crystalline lattice parameters of ATO. The transmittance of the ATO films varied between 75% and 85%. By employing the transmittance spectra and the established Tauc formula the optical bandgap values of ATO films were calculated, showing an increase in the bandgap with higher doping levels. These findings were thoroughly analyzed and discussed; additionally, an effort was made to clarify the contradictory analyses present in the literature and to identify a doping range that avoids the onset of a secondary phase.
