Strategy of nanocluster and nanostructure synthesis by conventional pulsedlaser ablation

We describe the basic principles of nanoparticle synthesis by conventional pulsed laser ablation. The generalization of the Zeldovich and Raizer theor y of condensation has been performed for inhomogeneous laser-induced plume where the rates of nucleation as well as the condensation times are differe nt for different parts of the plume. The theoretical development and analys is of the experimental results are given for condensation, expansion and pr operties of silicon nanoclusters. (C) 2000 Elsevier Science B.V. All rights reserved.
