In this paper, we report on the synthesis and characterization of hydrothermally synthesized ZnSe NCs. The influences of the synthesis parameters on the structure and optical characteristics of the obtained QDs were systematically investigated. The highest quality ZnSe NCs were achieved when the Zn:Se molar ratio was 1:1 and the reaction occurred at 190˚C for 20 hours. Our study shows the perspective for a large-scale, low-cost synthesis of ZnSe NCs for applications in solid-state lighting and photovoltaic devices. |
