<p>A method for preparing nanocrystals is disclosed. According to one aspect, the noncrystals include a semiconductor ternary compound consisting of the elements A, B and C. According to another aspect, the nanocrystals include a semiconductor of formula ABC2 optionally coated with a shell, the external portion of which includes a semiconductor of formula ZnS1-xFx, with A representing a metal or metalloid in the oxidation state +I, B representing a metal or metalloid in the oxidation state +III, C representing an element in the oxidation state −II, F representing an element in the oxidation state −II and x being a decimal number such that 0≦̸x<1. The disclosure also relates to the prepared nanocrystals and their uses.</p> |
