摘要: Abstract A simple electrochemical process has been demonstrated to grow highly oriented γ-CuI thin films on indium doped tin oxide (ITO) glass through reducing Cu(II)–ethylene diamine tetraacetic acid disodium (EDTA) complex in aqueous solutions at or near room temperature. The CuI preferential orientation along the 〈1 1 1〉 crystal axis from X-ray diffraction patterns. growth of is not affected by solution pH and applied potentials. possible mechanism discussed, surface energy different planes believed play an important role control films. bandgap electrodeposited 2.98 eV photoluminescence spectra exhibit relative intense exciton band luminescence
