Physical and chemical cross analyses of II‐VI semiconductor nanomaterials

Résumé

Abstract CdS quantum dots (QDs) are synthesized by the single source precursor thermal method. Compared with previous reports, a temperature ramp allows faster elaboration of smaller nanocrystals (NCs) with efficient room temperature (RT) visible emission. A cross‐disciplinary study between chemical analyses and physical techniques provides consistent data for these small NCs. Joint mass spectrometry, transmission electron microscopy and optical spectrometry techniques give a consistent picture about purity and stability of precursors, average size and size dispersion of the NCs, as well as their optical spectral response in correlation with their size via quantum confinement effects. RT photoluminescence spectroscopy reveals the great potential of such QDs and their tunable response wavelength in the visible spectrum. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
