Effect of laser energy on grain size of cadmium oxide nanoparticles in ethanol by PLD method

Abstract

The Pulse laser deposition technique was used in the preparation of nanoparticle solutions (CdO) using Nd:YAG laser and five deposition energies (400, 500, 600, 700 and 800 mJ) with fixed pulses (300 pulse and 6 Hz) was used .
 (CdO) nanoparticles were deposited on glass substrate at (300C°) to study structure properties and formed thin films of thickness (200 nm). The grain size of cadmium oxide nanoparticles in ethanol have been found to be affected by the laser energy , The results of the AFM tests showed that the higher the deposition energies, the greater the higher the grain size.
