Document Abstract
Vertically aligned and highly dense Zinc oxide (ZnO) nanorods (NRs) have
been successfully synthesized by a two-step hydrothermal method and decorated
by silver (Ag) nanoparticles (NPs) via a dip coating technique. Absorption
spectra indicate the presence of metal Ag NPs. The photoluminescence
(PL) spectrum of as-grown ZnO nanorods shows ultra violet (UV) emission
centered around 390 nm and a sharp defect-related emission peak around
580 nm. The presence of Ag NPs on the ZnO NRs shows a significant red shift
in PL peak position in the visible region and a complete quenching of UV
emission. The changes in UV–Vis and PL spectra of ZnO NRs decorated with
Ag metal NPs are studied and discussed.
