Color planar display thin film controlled by carbon quantum dot concentration and manufacturing method thereof

Abstract

The invention discloses a color panel display film with a function of concentration regulation of carbon quantum dots and a manufacturing method of the color panel display film. According to a wavelength dependence excitation photoluminescence characteristic of the carbon quantum dots, the carbon quantum dot film is enabled to emit light in different colors by regulation of dosage concentration of the carbon quantum dots. By taking the carbon quantum dots as materials of a luminescent layer and taking an ultraviolet light source as an excitation source, the carbon quantum dot panel display film variable in concentration distribution is prepared by means of adjustment of concentration of the carbon quantum dots on a polymethyl methacrylate hybrid layer to realize patterned and colored luminescence. The color panel display film has the advantages of high light saturation, long service life, nontoxicity, low preparation cost and environment friendliness. In addition, the color panel display film is simple in structure, the manufacturing method of the color panel display film is convenient to operate, shapes, depths and quantity of grooves in organic transparent glass can be adjusted according to colors, quantity and patterns in actual needs, multi-color luminescence can be realized, and application range is extremely wide.

Description

Technical field [0001] The invention relates to a flat display film and a manufacturing method, in particular to a color flat display film controlled by carbon quantum dot concentration and a manufacturing method thereof. Background technique [0002] Traditional display thin film materials mainly use rare earth materials (Eu 3+ , Tb 3+ Etc.), transition metal materials and their organic materials. As a new type of luminescent material that has been widely used in recent years, quantum dots have the advantages of higher luminous efficiency, longer service life, and better color purity than traditional display thin-film luminescent materials. At the same time, quantum dots can control the range of the emission spectrum by changing the size, excitation conditions and types, so as to realize the specific color of the light-emitting film. However, nowadays quantum dots are mainly used to emit light from heavy metal elements, such as cadmium sulfide (CdS), cadmium selenide (CdSe), le...
