Abstract The samples were pretreated by controlling PH in the process of Pechini, and after sintering and grind, the nano Eu-doped tungstate with different granularity was obtained in the result. The structure was characterized by XRD, and the diffuse scattering spectra and the crystal microstructure were characterized by HRTEM and spectrometer. It was found from high efficient decomposition of rhodamine that the nano-materials obtained have good catalytic effect of light.
