[Hydrothermal synthesis and luminescence of one-dimensional Mn(2+)-doped CdS nanocrystals].

One-dimensional Mn(2+)-doped CdS nanocrystals were synthesized by the hydrothermal route. The products were characterized by SEM, EDS, XRD, TEM, HRTEM and PL, respectively. The results revealed that dopant Mn2+ completely substitutes Cd2+ in CdS nanocrystals, and the product was of good crystallite.

[Preparation and spectral properties of PVP-modified CdS nanorods].

Polyvinylpyrrolidone (PVP)-modified CdS nanorods were prepared by a hydrothermal reaction of CdCl2 2.5H2O and (NH4)2S with 10 wt% ethylenediamine aqueous solution as solvent and 1.0 wt% PVP as additives.
