What is the reason for reduce in the average diameter of ZnO nanorod after Ti doping?

I have doped Ti in ZnO using a chemical method. The FESEM results are showing a reduction in the average diameter of ZnO nanorod after the Ti doping. Can someone help me to explain that? Thanks

What is the reason for blue shift of the Raman mode of ZnO after post growth annealing?

I have post-annealed ZnO nanorods in air ambient, the Raman results (E2(H) mode) show a blue shift to the high wavenumber. Can someone suggest me that how can I understand this case. Thanks

Why the PL intensity of ZnO nanorods increases after post annealing treatment?

Good time for all. ZnO nanorods were prepared using CBD and then annealed at air ambient. Why the PL intensity ( in the UV) enhances as annealed temperature increases.

Why measuring the optical energy band using UV-vis. gives different results of that measured using PL?

I measured the optical energy band gap (Eg) for doped ZnO using Uv-vis. Its results showed a red shift in Eg. However, the PL showed a blue shift in UV emission. The previous works reported...
