Abstract:
The present invention relates to a process for preparing nanoparticles of antimonides of metal element(s) in the form of a colloidal solution, using antimony trihydride (SbH3) as a source of antimony.
Abstract:
A nanocrystal particle includes a Group III-VI compound including gallium and sulfur, wherein the nanocrystal particle is configured to emit a first light, a maximum emission peak of the first light is in a wavelength range of greater than or equal to about 300 nanometers and less than or equal to about 485 nanometers, an absolute quantum efficiency of the nanocrystal particle is greater than or equal to about 26%, and a full width at half maximum of the maximum emission peak of the first light is greater than or equal to about 10 nanometers and less than or equal to about 70 nanometers, when analyzed by photoluminescence spectroscopy.
Abstract:
A method for producing a material based on silicon nanowires is provided. The method includes the steps of: i) bringing into contact, in an inert atmosphere, a sacrificial support based on a halogenide, a carbonate, a sulfate or a nitrate of an alkali metal, an alkaline earth metal or a transition metal having metal nanoparticles, with the pyrolysis vapours of a silicon source having a silane compound, by which silicon nanowires are deposited on the sacrificial support; and optionally ii) eliminating the sacrificial support and recovering the silicon nanowires produced in step ii).
