This invention provides a highly transparent nanocomposite film for ultraviolet-blue light protection and its preparation method. The aforementioned highly transparent nanocomposite film achieves a transmittance of less than 5% in the 250–500 nm ultraviolet-blue light band by precisely controlling the core-shell structure and energy levels of ZnCdS@Cd-rich nanocrystals through differentiated ligand ratios, coupled with a low filler content design of 0 < x ≤ 5 wt%. This results in highly transparent nanocomposite films that effectively shield high-energy harmful light radiation while maintaining a transmittance of not less than 90% in the long-wavelength visible light band above 520 nm, balancing protective effect and visual clarity. This solves the shortcomings of traditional materials that either provide insufficient protection or suffer from visual distortion due to poor transmittance. Furthermore, the preparation method is simple and controllable, requires no complex equipment, and is compatible with various coating methods such as drop coating, spin coating, and blade coating, making it suitable for large-scale production.
