Mn_xZn_1-xO Crystal Synthesized by Hydrothermal Method

Abstract:

Mn_xZn_1-XO Crystal was synthesized by hydrothermal method in this work.The experimental parameters for hydrothermal synyhesis were:Mineralizer concentration 3mol•L^-1KOH, the fill factor 35%, temperature 430°C, Zn(OH)₂ doped with MnO₂ as precursor, and the reaction time 24 hours. The Mn concentration in crystal was determined by X-ray EDS. The atomic percentage of Mn in crystal increases as the concentration of MnO₂ in precursor increased. The maximum atomic percentage for Mn is over 2%. The morphology shows characteristics of hexagonal prism of pure ZnO crystal. The exposed faces are hexagonal faces m｛10 0｝, hexagonal cone faces p｛10 1｝, negative polar faces ｛000 ｝and positive polar faces｛0001}. The diameters of the crystals are 50-200μm，the heights are 20-100μm.
