Vibrational Structures of Iodine-Vacancy Bismuth Oxyiodides Using Temperature-Dependent Low-Wavenumber Raman Spectroscopy

The reaction of BiOI to form iodine-poor derivatives under high temperatures was investigated by using temperature-dependent low-wavenumber Raman spectroscopy. The Raman spectra of BiOI and of the iodine-poor derivatives Bi4O5I2, Bi7O9I3, and Bi5O7I were recorded. The phonon mode displacement vector...
