α-MnSe crystallites through solvothermal reaction in ethylenediamine

α-MnSe crystallites were prepared by solvothermal reaction in ethylenediamine at 190 °C. X-ray diffraction gave the α-MnSe phase of product, X-ray photoelectron spectroscopy indicated the valence state of Mn2+ and Se2−. The flaky morphology was found by the transmission electron microscope images. The optimal synthetic conditions were explored by using other nitrogen-containing solvents, and lowering the reaction temperature.
