Abstract
A process for manufacturing colloidal nanosheet, by lateral growth, on an initial colloidal nanocrystal, of a crystalline semiconductor material represented by the formula MX, where M is a transition metal and X a chalcogen. The process includes the following steps: The preparation of a first organic solution, non or barely coordinating used as a synthesis solvent and including at least one initial colloidal nanocrystal; The preparation of a second organic solution including precursors of M and X, and including an acetate salt. And the slow introduction over a predetermined time scale of a predetermined amount of the second solution in a predetermined amount of the first solution, at a predetermined temperature for the growth of nanosheets. The use of the obtained material is also presented.
