Description

technical field [0001] The invention belongs to the technical field of novel displays, in particular to a method for calculating optical parameters of a monochromatic quantum dot color conversion layer of mixed scattering particles. Background technique [0002] The term "quantum dots" was coined in 1986, when they were first discovered in glass matrices and colloidal solutions by Alexey Ekimov and Louis Brus. Quantum Dots refers to semiconductor nanocrystalline materials with quantum confinement effect in three dimensions of space, also known as "artificial atoms". Quantum dots are mostly quasi-zero-dimensional nanomaterials composed of Ⅱ-VI or Ⅲ-V group elements. The size of the three dimensions is 1-10 nm, and the appearance is like a tiny dot. The electron transport inside the quantum dot is limited, the electron mean free path is very short, and the electron locality and coherence are enhanced, so the quantum confinement effect is particularly significant. Due to the ...
