Title:
LED AND METHOD FOR PREPARING THIN FILM
Document Type and Number:
WIPO Patent Application WO/2020/043147
Kind Code:
A1
Abstract:
An LED (1) and a method for preparing a thin film (3). The LED (1) comprises an LED chip (2) and a thin film (3) formed on the LED chip (2). The thin film (3) comprises a plurality of stacked carbon quantum dot layers (4) and PMMA layers (5) provided among the carbon quantum dot layers (4). The LED (1) and the thin film (3) adjust the number of layers of the carbon quantum dot layers (4) according to actual requirements by using the characteristic that the light emitting colors of carbon quantum dots in the carbon quantum dot layers (4) change along with different excitation wavelengths so as to adjust an overall light emitting color of a device, and the carbon quantum dots can be widely applied in display modules as fluorescent powder, and have large application potential.
