Abstract:
Our study describes a convenient one-step synthesis of ZnSe and ZnTe nanocrystals NC whose sizes and shapes are precisely tuned by varying the growth temperature or stabilizing surfactants. We utilized molecular precursors bisphenylselenolate or phenyltellurolatozinc -N,N,NN-tetramethylethylenediamine TMEDA, which effectively produce 0-dimensional sphere or 1-dimensional nanorods of ZnSe or ZnTe respectively. Nanocrystals are highly monodispersed and luminescent the emission wavelength varies over a wide range depending on the particle size. This study constitutes a nice demonstration of direct size and shape controlled synthesis of semiconductor nanocrystals and this method can be extended to the synthesis of nanocrystals of other materials,
