Samples of FeSe_1-xTe_x were prepared by conventional three electrodes method. Fe₂SO₄·7H₂O, SeO₂ and TeO₂ were used as solution. Preparation conditions were optimized to obtain a stoichiometric composition and a crystal structure for superconductivity. The composition and crystallinity of electrodeposited FeSe were very sensitive to the deposition potential and pH.
