Effects of bath temperature on the properties of chemical bath-deposited FeSxOy films

Iron-sulphide-oxide (FeSxOy) thin films were prepared on fluorine-tin-oxide (FTO)-coated glass substrate for 3-h-deposition times via chemical bath deposition (CBD) from an aqueous solution, containing 100 mM sodium thiosulphate (Na2S2O3), 30 mM iron (II) sulphate heptahydrate (FeSO4·7H2O) and 50 mM...
