| Abstract: | The TEM shows that the Si3N4 nanoparticles,which were prepared under carbon reduction,have a different diameter.While under different temperature.The infrared absorption spectra of Si3N4 nanoparticles measured that those have frequency shift and absorption's Widezation.The result proved that the infrared absorption spectroscopy of nanoparticles were blue shift and Widezation. |
