Abstract

A manufacturing method of a photo-induced enhanced quantum dot film comprises the following steps of: S1, providing a quantum dot base film, the quantum dot base film being an acrylic resin film containing quantum dots; S2, coating the quantum dot base film with a micron-sized silicon dioxide particle layer; S3, coating the quantum dot base film with acrylate glue; and S4, carrying out electron beam treatment on the quantum dot base film. The silicon dioxide microspheres dispersed on the surface of the base film can effectively generate total internal reflection, so that the photoluminescenceefficiency of the quantum dot base film is improved. Meanwhile, the quantum dot film has excellent water and oxygen isolation and wear resistance performances.

Description

technical field [0001] The invention relates to a method for making a photoinduced quantum dot film. Background technique [0002] Semiconductor nanocrystals with quantum confinement characteristics, also known as quantum dots, have unique optical and electrical properties due to their quantum size effects, such as continuously adjustable emission wavelengths, wide excitation spectra, narrow emission spectra, high Fluorescence quantum yield and photochemical stability, as well as anti-fluorescence bleaching, make it widely used in light-emitting diodes (LEDs), biological detection, lasers, and solar cell sensitizers, and significant research progress has been made in recent years. [0003] Quantum dot displays are devices that use quantum dot films as part of the panel architecture to generate monochromatic light to provide tunable primary colors and improve screen efficiency and performance. This can be achieved in two basic ways: photoluminescence and electroluminescence....
