Distorition of crystal lattice and abnormal infra-red behavior in nanocrystalline CaCO3
In this study, the structure of nanocrystalline CaCO3 was analyzed using TEM, SEM, FT-IR and XRD measurements. An unusually narrowv 3 band with remarkable blue shift about 40 cm−1 in the infrared spectrum was obs...
