Abstract:
Controlled preparation of Ni-doped ZnS (Zn1-NiS) nanocrystals with x ranging from 0 to 0.07 is explored in this study. Zn1-NiS nanocrystals were fabricated as surface-enhanced Raman scattering active substrates, and 4-mercaptobenzoic acid was chosen as the probe molecule to examine the surface-enhanced Raman scattering ability. The Zn1-NiS nanocrystals exhibited a prominent surface-enhanced Raman scattering ability and the maximum enhancement of the phenomenon was observed when x = 0.03. The amount of the surface defects caused by doping with Ni ions played a key role in the surface-enhanced Raman scattering ability. Our results demonstrate that the interaction between the semiconductor bands and the probe molecular energy levels can lead to novel charge behavior. The surface-enhanced Raman scattering ability is mainly attributed to its enhancement through the chemical (charge-transfer) mechanism. Furthermore, an interpretation of the mechanism responsible for the highly variable surface-enhanced Raman scattering enhancement has been proposed.

The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
