modified chemical bath deposition method

سنتز و ویژگی های نانو ساختار ZnO با روش رسوب حمام شیمیایی اصلاح شده

ABSTRACT

ZnO thin films were deposited using a simple, convenient and an inexpensive modified chemical bath method along with subsequent air annealing. There action mechanism for the growth of the ZnO nanostructure after theair annealing is also discussed. SEM observations reveal the formation of flower like nanostructures that are composed of leaf-like petals of thin nanosheets. The annealed ZnO nanostructures grow with the hexagonal crystalstructure. The ZnO nanostructure exhibits a blue shift in its optical absorption spectrum. The room temperature photo luminescence study reveals UV emission peaks due to near band edge emissions along withd efect related blue and green emission peaks.
