Bi-doped ZnO(BZO) powders of different Bi contents have been synthesized by co- precipitation method and characterized by TG–DTA, XRD, FT Raman, XPS, SEM–EDX, UV–visible and photoluminescence (PL) studies. X-ray diffraction data suggests the hexagonal wurtzite structure for modified ZnO crystallites and the incorporation of Bi3+expands the lattice constants of ZnO, while XPS spectra reveals the presence of Zinc and Bismuth in Zn2+ and Bi3+ oxidation states. The PL spectra suggest more number of oxygen vacancies in Bi-doped ZnO than bare ZnO. The photocatalytic performance of Bi-doped ZnO, compared to bare ZnO was examined by photo degradation (PCD) of Rhodamine 6G (Rh6G) in aqueous media under solar light. It has been found that Bi-doped ZnO showed better solar PCD efficiency than pristine ZnO..
