Abstract
Synthesis and Application of CdS nanocrystaline thin films
Yogesh V. Marathe and V. S. Shrivastava
In present investigation CdS nanocrystaline thin films were deposited on glass substrate by using two different methods i.e. sol gel and spray pyrolysis. Optical charecterisation of prepared nanocrystaline films was performed by UV Visible spectroscopy. Optical characterization indicates that film deposited by sol gel has band gap 3.25 and spray deposited film shows band gap 2.87eV. Prepared thin films then applied to the photocatalytic experiment of reduction of Cr (VI) from aqueous solution. Various process parameters have been studied in order to optimise efficient photocatalytic reduction of Cr (VI).
