اثر مدت زمان اکسیداسیون حرارتی لایه‏های نازک Zn فلزی بر روی مورفولوژی و خصوصیات ساختاری نانوسیم‏های اکسید روی

In this research, zno nanowires with high quality were synthesized by using thermal oxidation of metallic zn films. metallic zn films with the thickness of 250nm were deposited on glass substrate by pvd technique in vacuum. the deposited zinc films were annealed in air at temperature of 600?c for 30min, 1 h and 2 h in the tubular furnace. surface morphologies were characterized by scanning electron microscopy and results indicated that with increasing oxidation time, the length of zno nanowires increases.edx results revealed that only zn and o are present in the sample, indicating a composition of pure zno. xrd analyses demonstrated that zno nanowires have a wurtzite structure with orientation of (002).
