WebAs metal oxide, Bismuth ferrite (BiFeO 3) is a good semiconductor photocatalyst for environmental remediation due to its eccentric properties such as a multiferroic material, and ferroelectric properties. BiFeO3 has a visible-light band-gap, which makes it convenient for photocatalytic use. The sol-gel method WebBinary Compound Bismuth Sulphide (Bi2S3)are narrow band gap semiconductor with layered structure and are interesting and important because of major contribution in solar cells, photo detectors, Opto-electronic light amplifiers, Lasers, photo electronic cells. Thin films are grown by chemical bath deposition, chemical vapor Deposition technology.
