Mixed solutions, CuI and InCl3 dissolved in the mixture of the tri-octylphosphite and 1-octadecene and the sulfur dissolved in tri-phenylphosphite, were used as source solutions; the hexadecylamine was additionally mixed as a surfactant before the reaction. It was observed that the product CuInS2 NCs structurally transformed from the chalcopyrite(CP)-or zincblende(ZB)-to the wurtzite(WZ)-type depending on the amount of the surfactant and a storage time after the surfactant addition. Very weak photoluminescence in the near-infrared region was observed for the CP-or ZB-type NCs. This band was attributable to the electronhole recombination via defect levels. No photoluminescence was detected for the wurtzite-type NCs.展开更多
