Diffuse Reflection Mid Infrared Spectroscopy Study on the Structure of Natural Pink Sapphire
The structure of natural pink sapphire has been studied in situ using diffuse reflectance mid infrared spectroscopy.The experiment finds that the main infrared absorption modes of pink sapphire include:in the Al2O3 structure,the infrared absorption mode corresponding to the stationary Al3+ions sublattice vibration for O2-ions(νAl2O3-O-Al),in the Cr2O3 structure,the infrared absorption mode corresponding to the stationary Cr3+ions sublattice vibration for O2-ions(νC2O3-o-Cr)and in the Al2O3 structure,the infrared absorption modes corresponding to relative vibrations between Al3+ions(νAl2O3-Al-Al)The study of the structure of pink sapphire using diffuse reflectance mid infrared spectroscopy has certain application research value.
