Photoacoustic frequency and spectroscopy technique for evaluation opto-thermal properties of macromolecular nanostructures

Abstract

of great importance both from fundamental and applied points of view because these materials are promising in the field of nanowire materials in nano-optics and nanoelectronics. Theoretical investigations, which have recently done for macromolecular nanostructures, indicate different absorption properties as well as heat transport mechanisms for infra-red and visible incident beams. In order to enable experimental proving of theoretical models, we have suggested modification of optical pump part in classical photoacoustic frequency techniques and calculated matched electronic part. We have presented the technique for measurement optical coefficient of absorption and thermal diffusivity of macromolecular nanostructures at large range of infra-red and visible wavelength of pump beams.
