Zinc oxide (ZnO) is a commercially important material utilized in paints, rubber, catalysts, sensors, varistors, and so forth. ZnO exhibits semiconducting, piezoelectric, and pyroelectric properties. Nanorod structure ZnO has a potential for application in nanotechnology. Structural, morphological, optical, and electrical properties of ZnO can be changed drastically by its doping with various metal cations.
Hello Ram,
The advantage of nanorod structure over Thin Film of ZnO in terms of Optical Properties is their increased surface to volume ratio. The light absorption-area is increased due to the increased S to V ratio.
Dear Ram,
These type of hierarchical structures are very advantageous in optical and gas sensing point of view because of large surface area. Large surface area means more area is available to expose from the interact to light or gasses.
Ankit Soni Gaurav Malik Thanks for answers.
I want know which will one be more transparent vertical nanorods or poly- crystalline film? please suggest.
You can try UV-vis study on both this samples, then it would be easy to conclude.
Welcome dear Ram, I think the incident light will be trapped more in vertical nanorods in comparison of compact film due to high scattering. So, the transparency of the nanorods will be less comparable to film.
Gaurav Malik Thanks for your answer
What I think, since ZnO nanorod have property of more single crystalline than poly-crystalline threfore have less grain boundary and should be more transparent than poly crystalline film which has more grain boundary.
