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 |
