AB  - A set of samples of SrGd2O4 doped with Sm3+ and Dy3+with different concentrations was prepared via glycine-assisted combustion synthesis. All of the diffraction peaks are related to the pure orthorhombic lattice SrGd2O4, according to X-ray Powder Diffraction investigation. The Energy Dispersive X-ray Spectroscopy chemical characterization revealed that the structure included all desired elements. Field Emission Scanning Electron Microscopy was used to capture the morphology, which showed porous aggregated particles consisting of roughly 50 nm-sized spherical particles. The Mercury Intrusion Porosimetry was used to establish where voids originated, and the results showed that samples have a real permanent 3D pore structure. X-ray Photoelectron Spectroscopy verified the successful incorporation of Dy3+ and Sm3+ ions in the matrix. Down-conversion luminescence spectra were recorded and typical emission transitions were found for either Sm3+ (4G5/2→6H5/2, 4G5/2→6H7/2, 4G5/2→6H9/2) or Dy3+ (4F9/2→6H15/2 and 4F9/2→6H13/2) ions. Calculation of the energy band gap using UV-VIS Diffuse Reflectance Spectroscopy yielded values of 4.3 eV for both doped samples. Using UV-VIS Absorption Spectroscopy, the photocatalytic degradation process was observed. After 4 h of simulating Sun exposure, an analysis of the photocatalytic properties revealed that approximately 50% of the Rhodamine B had been mineralized.

AB  - Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM techniques were used for structural and morphological characterization of obtained samples. XPS spectra of mixed oxide samples were compared in order to correlate composition of samples with surface properties and presence of defects. Relative positions of defect states within band-gaps of semiconductors were estimated from UCPL spectra. UV-Vis DRS spectra revealed that both pure oxides experienced red shift of absorption thresholds compared to reference data. Photocatalytic activities of all samples were probed under simulated Solar light on three model compounds: phenol, 4-chlorophenol (4-CP) and 2, 4, 6-trichlorphenol (TCP). Pure TiO2 showed the highest photocatalytic activity in the case of phenol. However, pure ZrO2 and binary oxides showed higher photoactivity in degradation of 4-CP and TCP. The activity of wide band-gap semiconductors under simulated Solar light in photodegradation of phenol and its derivatives is most probably the consequence of formation of charge transfer complexes between pollutant molecules and semiconductors surface.
