In this study, the undoped, Erbium (Er) doped and Samarium (Sm) doped (1, 3, and 5 wt%) ZnO were synthesized using spray pyrolysis. X-ray diffraction patterns confirmed ZnO with strong diffraction peaks indexed in their ...

This paper reports on the deposition of pure and 5 at.% Al doped ZnO (AZO) prepared by sol-gel and applied to the substrates by spin-coating, and the role of annealing temperature on the crystallinity of these layers. It ...
