Characterization of AOT capped cadmium sulfide quantum dots using fluorescence spectroscopy

Colloidal cadmium sulfide quantum dots (Q-CdS) capped with dioctyl sulfosuccinate (AOT) were synthesized and characterized. Fluorescence spectroscopy is used to verify quantized dot formation, size, and emission wavelength. Optical characterization of this form is necessary for fundamental investigation of hybrid electronic materials and their potential use in next-generation devices. © 2010 Wiley Periodicals, Inc
