Chalcopyrite-type CulnS2 NCs was synthesized by the hot-soap method. Mixed solutions, Cul 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 CulnS2 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 nearinfrared 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. 相似文献
