“…This effect is related to the formation of Fermi levels within the band gap of TiO2 [36]. The 0.5%Ag-0.6%Mn/TiO2 photocatalyst showed a strong visible light absorption due to the synergistic effect from SPR of metallic Mn and Ag species.…”

“…The highest SBET value (165 m 2 /g) and large pore volume (0.47 cm 3 /g) are observed for the co-doped sample with 0.6 mol% Mn and 0.5 mol% Ag (Table 1). Large surface areas and high pore volumes are beneficial for pollutant adsorption and mass transport during the photocataytic reaction, respectively [36].…”

In this study, La and Mg doped, and co-doped ZnO nanoparticles were prepared using the sol-gel method. The prepared samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (DRS), and N2 physisorption techniques. The XRD results indicated that the prepared nanoparticles can be well adopted by the hexagonal wurtzite structure crystal and there are no second impurity peaks. Studies of the FESEM, EDX and TEM have shown that the samples have uniform spherical-like morphology with a homogenous distribution. The incorporation of La and Mg into the ZnO lattice had no effect on the morphology of the nanoparticles, but a reduction in the size of the grains (≈ 14 nm to ≈ 7 nm) was observed due to the insertion of these ions. The results of N2 physisorption indicated that there was an increase in BET surface area and pore volume for doped and co-doped samples. The results of DRS showed an increase in band gap energy and a blue shift at the absorption edge for doped and co-doped samples. The photocatalytic activity of the prepared catalysts was evaluated in the removal of RhB under UVA irradiation. The results showed that Mg5%-La5%/ZnO had the highest photoactivity (91.18 %) among all samples.

“…Because the ionic radii of Ga 3+ (0.0620nm, CN=8) are smaller than that of Al 3+ (0.0535 nm, CN=8) [20], the host lattice expands, and this indicates that Lu 3+ ions were successfully incorporated into the GdAlO 3 host lattices. The average sizes of the crystallites are estimated using Scherrer's equation [21]:…”

GdAlO3:Er3+, Yb3+ phosphors doped with Lu3+, Ga3+ ions were prepared via coprecipitation. The influences of substituting Ga3+ for Al3+ and substituting Lu3+ for Gd3+ on the structure and upconversion photoluminescence (UCPL) of the phosphors were studied. The experimental results show that the crystal textures did not change but the lattice parameters changed slightly via Lu3+, Ga3+ doping. This results in a decrease in the host phonon energy and a marked improvement in the green emission spectrum at 546nm. Moreover, the amounts of surface CO2, CO32-, and OH- species gradually decreased with Lu3+, Ga3+ doping. The combined effects led to an improvement in the UCPL efficiency with Ga3+, Lu3+ doping.
