Abstract

The invention belongs to the field of optical thin-films, and particularly relates to a quantum dot diaphragm array and application thereof. Aiming at solving the problem of higher costs of existing quantum dot diaphragms, the invention provides the quantum dot diaphragm array and the application thereof. The quantum dot diaphragm array comprises a plurality of quantum dot diaphragms, and the shapes of the quantum dot diaphragms are rectangular, strip-shaped or square; the quantum dot diaphragm array is formed by the quantum dot diaphragms. According to the quantum dot diaphragm array, a wholequantum dot diaphragm is replaced by the quantum dot diaphragm array to greatly reduce the costs, and the quantum dot diaphragm array has better stability and optical performance.

Description

technical field [0001] The invention belongs to the field of optical thin films, and in particular relates to a quantum dot film array and its application. Background technique [0002] Quantum dots are three-dimensional clusters with nanoscale size, so they are also called nanodots or nanocrystals. Due to the special structure of quantum dots, it has quantum size effect, macroscopic quantum tunneling effect, dielectric confinement effect and surface effect, thus producing unique physical and chemical properties and unique luminescent properties, which also makes quantum dot materials become a kind of materials related to It is an interdisciplinary field of physics, chemistry, optics, and nanomaterial technology. With the rapid development of semiconductor quantum dot synthesis, its advantages such as low cost, high stability, high quantum yield and large-scale production make it considered a solid foundation for further research on many frontier applications. Among them, ...
