Authors’ contributions XSJ and MZ prepared the films and tested the surface topography. X-ray diffraction was investigated by SWS and XPS. The surface morphology and optical properties were measured by GH and ZQS. The calculations were carried out by XSJ who also wrote the manuscript. Besides, MZ helped to draft the manuscript. All authors read and approved the final manuscript.”
