The carbon nanoparticles were analyzed with micro-Raman spectroscopy, UV-Vis spectroscopy and Electron microscopy. Optical limiting responses towards 532-nm wavelength were measured with a 7-ns Nd:YAG laser. Nanoparticle size and laser pulse repetition rate effects on optical limiting behaviour were studied. A model was proposed to explain the physical origin of this nonlinear optical process. This work can provide useful information for designing carbon nanoparticle based optical limiters. © 2007 IOP Publishing Ltd.||Source Title:||Journal of Physics: Conference Series||URI:||http://scholarbank.nus.edu.sg/handle/10635/51004||ISSN:||17426588||DOI:||10.1088/1742-6596/59/1/060|
