摘要：
In this work, we show a simple experimental procedure to obtain CdTe/CdS (diameter=3-7 nm) core shell nanocrystals in colloidal suspension. The nanocrystals were characterized by transmission electronic microscopy and powder X-ray diffraction analysis. The optical properties were determined by electronic absorption, excitation and emission spectroscopies and are discussed in terms of chemical changes that occur at the surface of the particles.
