Optical properties of petal-like aggregated nanocrystalline zinc oxide synthesized by laser ablation
The results of the investigations carried out on the third-order nonlinearity in zinc oxide (ZnO) nanocrystals (NCs) by Z-scan technique are included in this paper. ZnO NCs show negative nonlinearity and good nonlinear absorption behavior at 532 nm. The third-order optical susceptibility x(3) increases with enlargement of NCs due to the size dependent enhancement of exciton oscillator strength.
