The energy gap of ZnS QDs could be tuned as a function of the Gd doping concentration. The room-temperature electron paramagnetic resonance spectra of the Gd-doped ZnS QDs showed two resonance signals at g ≈ 2.052 and 2.813, which were attributed to the Gd (III) ions located at sites with weak and intermediate crystal fields, respectively. In addition, the as-synthesized Zn0.49Gd0.01S and Zn0.47Gd0.03S QDs displayed well-defined room-temperature ferromagnetism. The photocatalytic degradation rates of all the fabricated samples were assessed on the phenol red dye under the UV light illuminations.

Besides, this study aimed to investigate the effects of different surfactant such as SDS, CTAB, PVP, PVA, and oleic acid on the morphology and particle size of final products. Furthermore, the efficiency of BCTO nanostructures as the photocatalysts for the decolorization of rhodamine-B under ultraviolet light irradiation was evaluated. Moreover, FTO/TiO2/BCTO/Pt–FTO solar cell structure was used in order to find photovoltaic measurement by electrophoresis deposition. The solar cell results indicate that an inexpensive solar cell could be developed by synthesis of BCTO nanostructures through facile two-step sol–gel method.

The phase evolution, particle size and morphologies reported with respect to different concentrations of KOH as Mineralizer. And the photocatalytic activity and stability test of prepared samples was evaluated by degrading rhodamine B (Rh B) under visible light irradiation. 4 M KOH concentrations is the optimum condition to get single phase BiFeO3 and degradation efficiency was improved. The material shows strong stability and photocatalytic activity even after five recycling tests without losing it’s properties.

The crystal structure, surface morphology, and magnetic properties are investigated by X-ray diffraction(XRD), field emission scanning electron microscopy (FE-SEM), energy disperse X-ray analysis (EDAX), transmission electron microscopy (TEM), vibration sample measurement (VSM). The synthesized samples were used for the photocatalytic activity of Rhodamine B (RhB) dye under visible light irradiation and stability performance was examined by four cycles by the photodegradation test.
