Title: QUANTUM DOT MATERIAL, PREPARATION METHOD THEREFOR, AND SEMICONDUCTOR DEVICE
Abstract:
Disclosed are a quantum dot material, a preparation method therefor, and a semiconductor device. The quantum dot material comprises at least one quantum dot structure unit arranged in a radial direction in sequence. The quantum dot structure unit is a gradually-varied alloy component structure with energy level width varying in the radial direction or a uniform component structure with energy level width being consistent in the radial direction. A novel quantum dot material provided in the present invention not only achieves higher luminous efficiency of quantum dot materials, but also satisfies requirements of a semiconductor device and a corresponding display technology for comprehensive performance of the quantum dot materials, and is an ideal quantum dot light-emitting material applicable to the semiconductor device and the display technology.
