摘要
A method of producing a nanograin material wherein a hole-transporting surfactant is injected into an InP/ZnS dispersion solution, and the surface of an InP/ZnS quantum dot is covered with the hole-transporting surfactant to prepare an InP/ZnS dispersion solution with a hole-transporting surfactant. The InP/ZnS dispersion solution with a hole-transporting surfactant is then applied to a substrate using a spin coating process of the like to form a quantum dot layer with a hole-transporting surfactant having one or more layers. Then, a dispersion solution (replacement solution) containing an electron-transporting surfactant is prepared. The substrate having the quantum dot layer with a hole-transporting surfactant is immersed in the replacement solution for a predetermined time, and part of the hole-transporting surfactant is replaced with the electron-transporting surfactant to form a quantum dot layer having one or more layer.
