Abstract: A plurality of metal chalcogenide nanocrystals AnXm having an optical absorption feature above 12 μm and having a size superior to 20 nm. The metal A is selected from Hg, Pb, Ag, Bi, Cd, Sn, Sb or a mixture thereof. The chalcogen X is selected from S, Se, Te or a mixture thereof. The subscripts n and m are independently a decimal number from 0 to 5 and are not simultaneously equal to 0. Also, a method for manufacturing the plurality of metal chalcogenide nanocrystals AnXm, a material, a photoabsorptive film, a photoconductor, photodetector, photodiode or phototransistor, a device, the use of the plurality of metal chalcogenide nanocrystals, and a reflective or transmission filter.

Abstract: A method of preparation of mercury chalcogenide nanoparticles that includes the steps of providing a precursor of mercury and mixing the precursor of mercury with a precursor of chalcogenide, wherein the precursor of mercury is a mercury thiolate. Also, mercury telluride nanoparticles and their use in an IR photodetector, an IR photoconversion device, an IR filter or an IR photodiode.
