Preparation and characterization of CuInSe2 nano-particles

We had demonstrated that the morphology and particle size of CuInSe2 synthesized by a modified solvothermal route could be altered considerably by controlling the reaction temperature, reaction time and washing agents. The particle shape was spherical when deionized water was used as washing agent. Particles with the size down to 15 nm were obtained. When the washing agent changed to ethanol, nano-rods with the diameter ranged from 100 to 200 nm and the length of several micrometer were observed in the SEM.
