Two types of electrode configurations were employed in order to quantitatively examine the effect of gravitational strength on electrodeposited ZnO nanowire array: (a) a horizontal Cathode surface facing downward over an Anode (C/A) and (b) an Anode over a Cathode (A/C). The former configuration may simulate a quasi-microgravity environment, because macroscopic natural convection is not induced. Free standing ZnO nanowire array was successfully electrodeposited on ITO (Indium Tin Oxide)/FTO (Fluorine-doped Tin Oxide) substrate by template-free method in Zn(NO3)2 aqueous solutions. PL (Photoluminescence) of ZnO nanowire array was measured. Nanowire arrays with more uniform distribution of PL characteristics are synthesized in C/A configuration than in A/C. Seeding ZnO nanoparticles on ITO/FTO substrate can control the diameter as well as the orientation. Drop tower experiments are now planned.
