Abstract
We study in detail the synthesis
of CdTe nanoplatelets. Three populations
of nanoplatelets with a thickness defined with atomic precision are
obtained. We show that CdTe nanoplatelets can be extended laterally
to obtain nanosheets with lateral dimensions in the micrometer range.
We present the study of the reaction conditions for the formation
of CdTe nanoplatelets and for their lateral extension. The reaction
products are analyzed with
optical spectroscopy, transmission electron microscopy, and small-angle
X-ray scattering. We investigate the electro-optical properties of
films formed with CdTe nanoplatelets, and we show that their current
photoresponse is better than the one of comparable films formed with
CdTe spherical nanocrystals
