ZnO and TiO2 doped ZnO nanorod arrays have been synthesized using simple, low temperature and inexpensive chemical bath deposition procedures on silicon substrates. The FESEM results showed high-quality nanorods uniformly grown on the substrate surfaces. No defects issues were observed at the nanorods surface. The XRD patterns confirmed that the prepared samples possessed hexagonal wurtzite structure with preferred growth in the c-axis direction. The doped sample exhibited high (002) intensity with slight shifting towards the low angle in comparison with pure ZnO. The optical properties studied using PL system exhibited a strong enhancement in near band edge emission with blue-shifting in the doped sample as compared with pure ZnO. In addition, the visible emission in the doped structure was enhanced in comparison with ZnO. All the results of doped sample confirmed that the TiO2 can play a vital role in the improvement the physical properties of ZnO nanorods prepared using low temperature, inexpensive, and simple chemical bath deposition method on silicon substrates.
