Abstract
A white light quantum dot complex particle, comprising a seed particle (1) in the core, and a first shell layer (2), a second shell layer (3) and a third shell layer (4) wrapped around the seed particle (1) in order; in the first shell layer (2), the second shell layer (3) and the third shell layer (4) are one of a red light quantum dot layer, a green light quantum dot layer and a blue light quantum dot layer respectively, and are different from one another. Also disclosed is the process for preparing the white light quantum dot complex particle.
