One-step chemical bath deposition of Cu2O flowers grown on ITO seed layer coated glass substrate

Abstract

Here, the growth of Cu2O flowers on a glass substrate were successfully fabricated using one-step chemical bath deposition method at low growth temperature. These flowers were grown on ITO seed layers that were prepared on glass substrate by magnetron-frequency RF sputtering. The structure and surface morphology of the products of Cu2O flowers were characterized in detail using X-ray diffraction and microscopy of field emission scanning electron. Optical properties were examined through the ultraviolet/visible spectro-scopy. The results showed that the Cu2O flowers were uniformly formed on ITO seeds-coated glass substrate, grow in the cubic structure with film preferential (111) plane orientation, high transmittance, and good crystallinity. The value of band gap is approximately 2.53 eV. This study helps to be the basis for more research on the growth of Cu2O at low-temperature and low cost-effective substrate.
