Pulsed laser deposition of zinc nanostructures and their nonlinear optical characterizations

摘要

In this work, preparation of zinc nanostructured thin films using the pulsed laser deposition (PLD) technique has been described. Optical absorption spectera of the thin films have been obtained by Spectrophotometry. Morphology and mean size of nanoparticles in the prepared nanostructured thin films were obtained by Atomic Force Microscopy. Nonlinear optical properties of the films have been investigated using the well-known Z-scan technique. Our measurements indicate positive signs for both nonlinear optical absorption coefficients and refraction indices of the nanostructured zinc thin films. The used method for measuring the optical limiting properties of the thin films and its results are also represented.
