Title:
METHOD FOR SYNTHESIZING CARBON QUANTUM DOTS, AND METHOD FOR MANUFACTURING UV LIGHT- AND BLUE LIGHT-BLOCKING FILM
Document Type and Number:
WIPO Patent Application WO/2020/246784
Kind Code:
A1
Abstract:
The present invention relates to a method for synthesizing carbon quantum dots capable of effectively blocking UV light and blue light from application devices composed of white LEDs, and a method for manufacturing a UV light- and blue light-blocking film, and the method for manufacturing a UV light- and blue light-blocking film, of the present invention, comprises the steps of: hydrothermally synthesizing a liquid hydrocarbon aqueous solution in a high-pressure reactor; dispersing the synthesized product in a polymer aqueous solution; and applying a dispersion solution, and then drying same.
