摘要
We present a facile approach for synthesizing bio-stabilized CdS nanoparticles in gram quantities. The particles were characterized by optical spectroscopy, Raman spectroscopy, soft X-ray emission spectroscopy, XRD, thermal and chemical analysis. The size of the particles is about 2.3 nm, with a CdS core of 1.3 nm diameter and an organic shell of 0.5 nm thickness which is thermally stable up to 200 degreesC. The chemical composition, surface termination, and optical proper-ties are analysed. (C) 2003 Elsevier B.V. All rights reserved.
