Preparation and Properties of CdS Nanoparticles Stabilized by Sulfonated Polystyrene |
| 초록 |
CdS nanoparticles have been prepared by using sulfonated polystyrene (SPS). CdS nanoparticles could be obtained by the reaction of SPS with CdCl2 and Na2S in toluene. Transparent solution of CdS/SPS in toluene exhibited absorption max. at 400 nm in uv spectrum. Upon excitation with a light of 400 nm, an emission band maximized at 470 nm was observed from fluorescence spectrum. The λ max. of the emission band from CdS nanoparticles is considerably blue-shifted relative to the emission onset of bulk CdS (515 nm), indicating the formation of nanosized CdS particles (~5 nm). Transparent thin films could be prepared from the CdS/SPS solution. The films showed photocurrent of 1.8 μA/cm upon exposure to a light source of 365 nm. The structure of CdS in SPS nanocomposite was further characterized by TEM. |
