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.
