Preparation of zinc oxide nanorods using pulsed laser ablation in water media at high temperature.

چکیده
ZnO columnar single crystals were formed by pulsed laser ablation in deionized water and surfactant aqueous solutions of lauryl dimethylaminoacetic acid (LDA) and cetyltrimethylammonium bromide (CTAB) at 80 degrees C. ZnO particles produced by laser ablation were dissolved at a higher temperature than 60 degrees C, and then crystalline growth to columnar structure proceeded. While large ZnO columnar crystals were obtained in deionized water, the crystals prepared in surfactant solution were smaller than those in deionized water due to inhibition of crystalline growth by surfactant adsorption on ZnO surfaces. The size of ZnO nanorods depended on how surfactant molecules adsorb on ZnO surface.

ZnO thin films of porous structure with strong c-axis orientation were deposited on n-type silicon substrate by pulsed laser ablation of ZnO target in low O2 pressure (around 0.03 mbar) and at 600C substrate temperature. We attribute the formation of nanopores and the crater-like formation to the high kinetic energy of the ablated particles. Photoluminescence spectra show the near band edge emi...
