Use of the photoacoustic spectroscopy for surface characterization of nanometer-sized cobalt-ferrite particles

Abstract

Photoacoustic spectroscopy was used in the investigation of cobalt ferrite nanosized particles (about 5 nm in diameter) surface-uncoated or surface-coated with different species. The surface-coated nanoparticles display well defined photoacoustic features in the wavelength region typical of d-d transitions of the transition element ions. Removal of the… (More)
