The preparing process is described as follows:(1) the raw materials are dispersed in the solvent;(2) the solution is arranged between two electrodes;(3) alternating current with a voltage of 5 V-100V and a frequency of 10Hz-1000Hz is applied to both ends of the electrodes for 5minutes to one hour;(4) the product obtained after being washed with deionized water and pump filtrated or after centrifugal treatment is dried by being heated to 40 centigrade to 100 centigrade to get the nanometer grain, wherein the raw materials in the first step are micrometer materials or nanometer materials such as sulphide, selenide, telluride and oxide; without special requirement on shape or appearance, the materials can be in the shape of a rod, a fork, a star, a block or a sphere; the solvent in the first step can be water, ethanol, acetone, benzene or tetra chloromethane.

步骤为：1将原料分散于溶剂中；2使制成的溶液处于两电极之间；3在电极两端的加交流电，电压为5V-100V，频率为10Hz-1000Hz，时间为5min-1h；将产物用去离子水洗涤、抽滤，或进行离心处理后；4将所得到产物加热到40～100℃进行干燥，得到纳米颗粒。步骤1中原料为硫化物、硒化物、碲化物、氧化物等微米或纳米材料，其形貌不限，可以为棒状、枝状、星状、块状、球形等多种形状。步骤1中的溶剂可以为水、乙醇、丙酮、苯或四氯化碳。
