transformation into a highly stable orthorhombic structure were confirmed by thermal studies. The optical band structure and ethanol vapor-sensing behavior were studied by means of diffusereflectancespectroscopy (DRS) and fiber optics spectroscopy, respectively. To the best of our knowledge, this paper reports
