Abstract
A quantum dot including a core including a quaternary alloy semiconductor nanocrystal and not including cadmium, a composition and a quantum dot polymer composite including the same, and an electronic device including the same.The quaternary alloy semiconductor nanocrystal comprises indium (In), phosphorous (P), zinc (Zn), and selenium (Se), and in the core, a ratio of the zinc with respect to the indium is less than or equal to about 0.5:1 and in the core, a ratio of selenium with respect to zinc is less than or equal to about 0.6:1.
