Two-dimensional(2D)few-layer VSe2,V1-xFexSe2 nanosheets have been synthesized by a high-temperature organic solution-phase method.The thickness of VSe2 nanosheets can be tuned from 12 to 5 layers by decreasing the precursor concentrations.The few-layer VSe2 nanosheets show the room-temperature ferromag-netism.The coercivity and magnetization reach 0.024 T and 0.036 mA·m2·g-1 at room temperature.The charge-density wave behavior is also confirmed in VSe2 by the hysteresis loops and zero-field-cooling curve.V1-xFexSe2 nanosheets can be obtained by doping Fe(acac)3 in the reaction process.The room-temperature coercivity and magnetization of V0.8Fe0.2Se2 nanosheets are 5 times higher than those of the pure VSe2 nanosheets without destroying the structures.The enhancement of magnetiza-tion is due to the coupling interaction of 3d orbits between V and Fe atoms.Higher Fe concentration is beneficial to improve the coercivity,which is attributed to the formation of the second phase Fe3Se4.This simple chemical prepa-ration method can be extended to prepare the other 2D materials.
