Abstrakt:

CdS nanoparticles embedded in Nafion membranes were studied by a vartiety of optical spectroscopic methods. Quantum confinement was achieved (particle mean diameter of 40A) and the growth was found to follow a linear temporal kinetic law. Discrete energy levels were observable, even at room temperature. They could be attributed to light hole and heavy hole 1S and 2S transitlons.The experimental results are in good agreement with theoretical calculations of light hole and heavy hole masses in the cases of cubic CdS. An enhancement of the nonlinear susceptibility x(3) at the quantized excition energy levels was observed. The clusters were found to be photo-unstable, with a diffusion-limited growth rate due to Ostwald ripening.
