Title:
ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/176088
Kind Code:
A1
Abstract:
In the present invention, a luminescent element (1) is provided with a positive electrode (12), a negative electrode (17), and a quantum dot (QD) layer (15) that contains quantum dots (25) and is disposed between the positive electrode and the negative electrode. The quantum dots are Cd-free quantum dots, either AgInxGa1-xSySe1-y-based or ZnAgInxGa1-xSySe1-y-based (0≤x<1, 0≤y≤1), and, in the green wavelength to the red wavelength regions, exhibit fluorescent properties that include a fluorescence half-width of 45 nm or less and a fluorescence quantum yield of 35% or greater .
