通过一次反应可制备出10g以上的热电用Cu2ZnSnSe4胶体纳米晶。由胶体纳米晶制备的颗粒在450℃时的ZT值为0.44，与目前最先进的Cu2ZnSnSe4基块体材料在相同温度下的ZT值相似。
Over 10 g of non-stoichiometric Cu2ZnSnSe4 colloidal nanocrystals for thermoelectric applications are prepared after one single reaction. The obtained pellet made from the colloidal nanocrystals shows a peak ZT value of 0.44 at 450 degrees C, which is similar to those of state-of-the- art Cu2ZnSnSe4-based bulk materials at the same temperature.
