利用ＴＥＭ、ＳＥＭ、Ｘ射线衍射（ＸＲＤ）和Ｖｏｉｇｔ函数单峰分析法讨论了纳米ＣａＣＯ３ 微晶结构，解释了纳米ＣａＣＯ３ 微晶的反常红外吸收特性，并认为微结构中的尺寸效应使得纳米ＣａＣＯ３ 晶格中存在较大的畸变应力，从而引起了碳酸钙微晶的红外ν３ 吸收峰有约４０ ｃｍ － １的蓝移和明显窄化。
The microcrystalline structure of nano-CaCO3 was discussed by TEM, SEM, X-ray diffraction (XRD) and single-peak analysis by Voigt function, and the anomalous infrared absorption characteristic of nano-CaCO3 crystallites was explained. The size effect of nano- There is a large distortion stress in the lattice, which leads to a blue shift of about 40 cm - 1 and an obvious narrowing of the ν3 absorption peak of calcium carbonate crystallites.
