Summary: The synthesis of Sn1-xAlxO2 (x = 0.0, 0.01, 0.02, 0.03, 0.04) nanoparticles by the sol-gel method and their characterization using various techniques revealed that increasing the aluminium content led to a decrease in the crystallite size and optical band gap. Photoluminance measurements showed violet emissions for all samples, with the 3% doped sample exhibiting the lowest intensity, indicating its potential for applications in photocatalysis and lithium-ion batteries. Additionally, 3% aluminium doping was found to be the optimum concentration for tin oxide samples in photocatalytic applications.

Summary: Sm3+ activated Y4Al2O9 nanophosphors were synthesized using urea aided gel-combustion route. The nanosamples exhibit monoclinic crystal structure with P21/c space group. Under excitation at 406 nm, the Y4Al2O9:Sm3+ nanophosphor emits reddish-orange light with emission peaks at 566 nm, 602 nm, and 651 nm corresponding to transitions 4G5/2 -> 6H 5/2, 6H 7/2, and 6H 9/2, respectively. The optimal dopant concentration is observed to be 3 mol%, and dipole-quadruple interactions among dopant ions contribute to concentration quenching. Evaluation of chromaticity parameters, color temperature, and color purity suggests the potential applicability of these nanophosphors for indoor lighting applications.

Summary: Mist-assisted methods in plasma deposition of high-quality thin films have recently gained attention, but little is known about plasma interactions with misted colloidal solutions. Time-resolved optical diagnostics were used to study the deposition of TiO2-SiO2 nanocomposite thin films in low-pressure oxygen-argon plasmas. The presence of nanoparticles in misty plasma effects were dominated by plasma droplets, not plasma-nanoparticle interactions. Subsequent matrix-rich and nanoparticle-rich deposition steps were confirmed using in situ spectroscopic ellipsometry.

Summary: This study investigates the effect of plasma treatment and thermal annealing on the morphology and composition of silver nanoparticle thin films. The results show that both treatments result in a decrease in isolated nanoparticles and the formation of polygonal structures with sharp corners and edges. The main absorption band of the silver nanoparticles experiences a redshift after treatment, and surface oxidation occurs. Only the plasma-exposed samples exhibit a significant increase in the surface-enhanced Raman scattering signal. Large-scale micrometer domains with sharp corners and edges control the surface-enhanced Raman scattering signal.

Summary: Au/TiO2 photocatalysts were studied and compared for gas phase reduction of CO2. The nature of the TiO2 support was found to significantly affect the performance of the catalyst. Among the studied catalysts, the 0.84 wt.% Au/TiO2 SG (Sol Gel) calcined at 400 degrees C exhibited the best performance, which could be attributed to its large surface area, high density of exposed (101) anatase TiO2 facets, and oxygen vacancies acting as reactive defects sites.

Summary: WSiC:H coatings were prepared by reactive magnetron sputtering in an Ar/Si(CH3)4 plasma assisted by ECR microwave sources. These coatings have great potential for optical or mechanical applications. The development of these coatings is based on the correlation between in-situ diagnostics of the reactive plasma phase and the characterization of the resulting coatings. Optical emission spectroscopy identified a precursor flow rate range where W particles can be favored in the reactive plasma, facilitating the formation of composite coatings with a SiC:H matrix containing W-containing particles or aggregates. Material characterization techniques, like Scanning Electron Microscopy, Ion Beam Analysis, and X-ray Photoelectron Spectroscopy, were used to study the influence of the plasma phase on the microstructure and chemical composition of the deposited materials.
