Abstract
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.
Claims11
A method for producing a lead chalcogenide nanocrystal, the method comprising contacting a lead (IV) containing compound starting material with an organic acid and a chalcogen-containing reagent,
- wherein the lead (IV) containing compound has a molar ratio of lead (IV) to lead (II) of greater than 1:1,
- wherein the lead (IV) containing compound is contacted with the organic acid to produce a lead salt and the lead salt is contacted with the chalcogen-containing reagent,
- wherein the organic acid is a fatty acid, and
- wherein the chalcogen-containing reagent is selected from a sulphur-, selenium- and tellurium-containing reagent, and mixtures thereof.
