NOVEL PROCESS USING OXYGEN AND AIR BUBBLING IN CHEMICAL BATH DEPOSITION METHOD FOR VERTICALLY WELL ALIGNED ARRAYS OF ZnO NANORODS

Vertically well-aligned ZnO nanorods arrays have been synthesized on ZnO seed layer coated glass substrates at low temperature using modified low-cost chemical bath deposition (CBD) method. The investigation of the influence of no air bubbles, air bubbles and oxygen bubbles inside the CBD reactor on the structural characteristics, morphological (diameter, length, aligned, distribution and homogeneously), elements chemical composition and optical properties of ZnO nanorods have been studied. This new modification of chemical bath deposition method shows the improved results over traditional chemical bath deposition method. The important results of this novel process are the good morphological, structural characteristic and optical properties of ZnO nanorods. These results obtained in just of 3.5 h growing time in the CBD reactor. On this modified CBD the growth time rate decreases about 1.5 h compared with the previous works.
