摘要
We have studied the effect of ageing on the photoluminescence of uncapped CdS nanocrystals prepared using a chemical route. Two luminescence bands in the energy range 1.55-2.48 eV were observed whose intensities were found to increase with ageing. The luminescence properties obtained for different excitation are also presented. (C) 1999 Elsevier Science Ltd. All rights reserved.
