Molecular precursor route for the phase selective synthesis of α-MnS or metastable γ-MnS nanomaterials for magnetic studies and deposition of thin films by AACVD

Colloidal Synthesis of γ-MnS Nanorods with Uniform Controlled Size and Pure ⟨002⟩ Growth Direction

“…MnS is one of the most important metal chalcogenide semiconductors with a wide bandgap, which has great potential applications in short wavelength photonics, optoelectronics, and magnetics. − MnS exists in three crystalline forms such as the green stable rock salt α-phase, pink metastable zinc blende β-phase, and pink metastable wurtzite γ-phase. Besides the most reported stable α-MnS nanostructures, ,, the metastable γ-MnS nanostructures had been also reported via the solvent thermal and the chemical vapor deposition methods. − Recently, the seeds-mediated method was also used to synthesize γ-MnS nanostructures, where the preformed Ag 2 S and Cu 1.94 S nanoparticles often acted as the seeds. − And the cation exchange reaction was used to form γ-MnS by employing djurleite Cu 1.94 S nanoparticles as the starting templates . However, it was still challenging to control the growth direction of metastable γ-MnS nanostructures at a large scale, which was significant for application of the anisotropic nanomaterials.…”
