Hydrothermal Synthesis of Diluted Magnetic Zn1-xMnxO Semiconductor

摘要：

　　Diluted magnetic semiconductor Zn1-xMnxO crystals were synthesized at 430℃ fbr 24h by hydrothermal method.3mol.L1KOH was used as the mineralizer,and the fill factor is 35%.The obtained crystals show a ZnO wurtzite structure,with positive polar faces0001 ,negative polar faces000 (1) ,p faces (1) 011 and-p faces (1) 01 (1) exposed.The height of the crystal is 5-30 μ m and radius-height ratio is2:l.Mn atom concentration of 2.6% (x=0.026) was determined using X-ray energy dispersive spectroscopy (EDS).The crystals show low-temperature ferromagnetism with Curie temperature of 50K.
