CdSe/ZnO Core/Shell Semiconductor Nanocrystals: Synthesis and Characterization

Abstract:

CdSe/ZnO core/shell semiconductor nanocrystals which show high luminescence quantum yield have been synthesized through a simple routine without the use of any pyrophoric organometallic precursors. Transmission electron microscope image demonstrates the shape, monodispersity, average size, size distribution and core-shell structure of CdSe/ZnO nanocrystals. We use a combination of X-ray diffraction, UV-Vis absorption spectroscopy and photoluminescence to analyze the core/shell nanocrystals and determine their chemical composition, optical character and internal structure.
