Mg selenide formula is a chemical formula that is brown in color and is a crystalline solid. It is a compound that can be found in minerals such as brucite, carnallite, dolomite and magnesite.
MgSe nanocrystals are a potential application for a variety of applications, such as photovoltaic solar cells. They are also useful in other industrial processes, including in the production of pharmaceuticals and food products.
A method for synthesizing a Mg-Se nanocrystal according to an embodiment includes reacting a first precursor containing magnesium and a second precursor containing selenium in the presence of a ligand compound in an organic solvent. The ligand compound does not include an oxygen functional group and may be a carboxylic acid, a hydroxyl group, or a carbonyl group.
In this way, the oxophilic character of magnesium does not hinder the reaction between the Mg-Se nanocrystal and the oxygen functional group of the ligand compound. This process is preferably carried out in an inert atmosphere.
The process is further characterized by using a third precursor that contains a metal element selected from the group consisting of Zn, Ga, In, S, and Te, or a non-metal element selected from a Group II metal, a Group III metal, a Group V non-metal element, or a Group VI non-metal element other than Se, such as a metal powder, an alkylated metal compound, a metal halide, a metal cyanide, or a combination thereof.
The crystalline phase of the nanocrystal represented by Chemical Formula 1 is an amorphous material that has a phonon density of states (PDOS) and a phonon dispersion in the ZB, WZ, RS, and NiAs crystalline phases. It has lattice constants, bulk modulus, Young’s modulus and shear modulus that are in good agreement with previously reported values for MgSe based on a Voigt- Ruess-Hill approximation.
