Abstract

Monosized and anisotropically capped CdS nanocrystals have the property to self-connect into a polymeric material. The viscosity of this fibrous material can be adjusted to fabricate texturized and homogeneous coatings. These films can be thermally converted into pure CdS films. Based on the size dependent band gap of this semiconductor, the absorbance of the film can be fine-tuned through the size of the particle-precursor or by controlling the film heat treatment. The evolution of the film nanostructure with temperature was investigated by optical absorption, DTA, SEM and X-ray diffraction techniques.
