| 摘 要： | 以乙二醇、乙醇为溶剂通过溶剂热法制备出立方状ITO纳米粉体,研究了反应时间、NaOH浓度对ITO纳米粉体形貌的影响,并讨论了溶剂体积比、NaOH浓度对ITO粉体导电性的影响及机理。结果表明:采用乙二醇与乙醇做溶剂,V_(EG)∶V_(EtOH)=4∶1时,制备出分散性良好的立方状ITO纳米粉体,平均粒径为10.7 nm,且其XRD衍射峰强度比I_(400)/I_(222)最高为0.380;乙二醇与乙醇做溶剂,V_(EG)∶V_(EtOH)=4∶1,且NaOH浓度为0.275 mol·L~(-1)时,粉体电导率最高为46.75 mS·cm~(-1)。

| Abstract: | Using ethylene glycol, ethanol as mixed solvents, cubic shape ITO powders were synthesized. The effect of reaction time, the concentration of NaOH on the phase and the morphology of ITO powders was investigated, and their influence on the electric conductivity and the mechanisms of ITO powders were also discussed. The results show that using the ethylene glycol and ethanol as mixed solvents, VEG:VEtOH=4:1, the cubic shape ITO powders with good dispersancy are prepared, the average particle size is 10.7 nm, and the XRD diffraction intensity ratio I400/I222 gets up to 0.380. when the ethylene glycol and ethanol act as mixed solvents, VEG:VEtOH=4:1, and the concentration of NaOH is 0.275 mol·L-1, the electric conductivity of the powder gets up to the maximum 46.75 mS·cm-1. |
