Abstract
(EN)
The present invention provides the use of a lead (IV) containing compound to prepare a lead chalcogenide nanocrystal and a method for producing broadband lead chalcogenide nanocrystals in a low cost, size-controllable and scalable method, the method comprising contacting a lead (IV) containing compound with an organic acid and a chalcogen-containing reagent.
(FR)
La présente invention concerne l'utilisation d'un composé contenant du plomb (IV) pour préparer un nanocristal de chalcogénure de plomb et un procédé de production de nanocristaux de chalcogénure de plomb à large bande à faible coût, le procédé comprenant la mise en contact d'un composé contenant du plomb (IV) avec un acide organique et un réactif contenant du chalcogène.
