Abstract
Stable colloids of ZnO quantum dots are prepared by the chemical solution method by capping with a common polyelectrolyte dispersant, polyethylene imine. The influence of PEI in arresting the particle growth is investigated through time-dependent absorption spectroscopy. The stable colloid thus produced is found to exhibit excellent third-order nonlinear optical properties as revealed by Z-scan studies.
