摘　　要：采用漫反射中红外光谱原位开展了天然粉红蓝宝石结构的研究.实验发现:天然粉红蓝宝石主要红外吸收模式包括:Al_(2)O_(3)结构中O^(2-)离子对于静止Al^(3+)离子亚点阵振动对应的红外吸收模式(ν_(Al2O3-O-Al))、Cr2O3结构中O^(2-)离子对于静止Cr^(3+)离子亚点阵振动对应的红外吸收模式(ν_(Cr2O3-O-Cr))和Al_(2)O_(3)结构中Al3+离子之间相对振动对应的红外吸收模式(ν_(Al2O3-Al-Al)).利用漫反射中红外光谱开展粉红蓝宝石结构研究具有一定的应用研究价值.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 Al_(2)O_(3) structure,the infrared absorption mode corresponding to the stationary Al^(3+)ions sublattice vibration for O^(2-)ions(ν_(Al2O3-O-Al)),in the Cr2O3 structure,the infrared absorption mode corresponding to the stationary Cr^(3+)ions sublattice vibration for O^(2-)ions(ν_(C2O3-O-Cr))and in the Al_(2)O_(3) structure,the infrared absorption modes corresponding to relative vibrations between Al3+ions(ν_(Al2O3-Al-Al)).The study of the structure of pink sapphire using diffuse reflectance mid infrared spectroscopy has certain application research value.
