Description

Infrared (IR) transmittance spectra were measured for a series of La2/3Ca1/3MnO3 samples with different particle sizes. Two extra absorption peaks appear when the average particle size of the samples is smaller than 60 nm; these peaks can be ascribed to the surface stretching and bending modes of the MnO6 octahedra. When the average particle size decreases, the absorption strength of the surface modes increases while that of the bulk modes reduces. (author)
