Abstract :In this work, we studied optical, photocatalytic and photoelectrochemical properties of a series of lanthanide-doped double layered Aurivillius type bismuthoxides. The visible-light harvesting photocatalysts doped with Eu, Pr, Nd, Tm, Ho and Ceions were synthesized by solid-state synthesis method using lanthanide precursors ranging from 0.2 to 10 mol % and were characterized by X-ray diffraction insert ignore into journalissuearticles values(XRD); and scanning electron microscopy insert ignore into journalissuearticles values(SEM);. Furthermore, luminescence of Pr and Euion doped catalysts are evaluated. Photoelectrochemical behaviour of the powders was also investigated. Best photoelectrochemical response is achieved with Tm ion doped sample.
