X-ray diffraction measurements showed that ZnO<br>nanofibers have pure hexagonal wurtzite structure. The effects of flow rate<br>parameter on ZnO nanofibers were examined using atomic force<br>microscopy, field emission scanning electron microscopy. The optical<br>energy gap was estimated and optical behavior was studied using UV-Vis<br>spectroscopy. It was found that the optical energy gap is (3.9) eV. It was<br>noted that the average diameter of these nanofibers increases from (82-132)<br>nm with increasing the flow rate from (1- 3) ml/h respectively. The length<br>of the nanofibers reached to several microns.</p>}, number={5}, journal={مجلة المستنصرية للعلوم والتربية}, author={Muhsin A. Kudhier and Raad S. Sabry and Mushtak A.
