摘要

A quantum dot structure has a matrix layer, and first quantum dots and second quantum dots provided within the matrix layer. The second quantum dots are arranged cyclically in the thickness direction of the matrix layer so as to be located in between first quantum dots, and the first quantum dots are smaller than the second quantum dots. The first quantum dots and the second quantum dots have different compositions, and using A to represent the electronegativity of the first quantum dots and B to represent the electronegativity of the second quantum dots, the relationship between the two is A < B.
