Optical limiting properties of In2O3 nanoparticles under cw laser illumination

Abstract We have measured the effective intensity dependent nonlinear coefficient n 2 of In 2 O 3 nanoparticles with surface modification by Z-scan technique. The optical limiting properties of coated In 2 O 3 nanoparticles under cw laser illumination were investigated. Novel absorption at different wavelengths as a function of incident intensity was observed.
