I have prepared aggregated ZnO nanowires by co-precipitation. When doped with metal ions the morphology distorted from nanowires to another morphology. Kindly suggest me any article related to the morphology change of ZnO with doping. Also help me to identify the morphology of doped ZnO.
Both the images of undoped and doped are attached here.
Why don't you use the same scales for two images? This can be seen from the scale bars for each image.
@Xuhua Wang The morphology is changed irrespective of zooming. I uploaded the best images of both these samples.
@Hadi Jabbar Alagealy can you send me the links of such articles if you know
Dear Muhammad Usman Khalid ,
Hope you are well.
The doping affects the morphology of deposited film as it can affect the process of seed formation and the further growth of the seeds. Most probably is that it enhances the seeding process and therefore the crystallographic structure will be in form of grains. To form fibers one must reduce the tendency to seed formation.
This will lead to smaller number of seeds and their subsequent growth inform of wires.
So, the pictures shows that the presence of impurities will enhance the formation of seeds and retard their further growth as a wire.
You study further the effect of varying the doping concentration on morphology.
I do no how much is your doping concertation.
If my interpretation is valid you may find a change in the density of the wires with concentration.
Best wishes
