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.

What is the reason for increase in the crystallinity of ZnO after Ti doping?

I have doped Ti in ZnO using a chemical method. The XRD results are showing an increase in the intensity of ZnO peak after the Ti doping. These results are also supported by the results obtained...
