Scientists have developed a technology for the production of transparent, luminescent material, which will make screens of smartphones and TVs with flexible, unbreakable, and the image is more realistic.
The material is a thiol-alkina nanocomposite polymer that holds light-emitting quantum dots — tiny energy-efficient semiconductors, the size and composition of which can be changed to obtain bright and clear colors.
The achievement of researchers from the US Naval Laboratory is that with the help of the new ligand they managed to firmly link the Tiol-INO polymer with CT and evenly distribute it throughout the matrix.
The material can be polymerized with ultraviolet light or thermal curing. This allows you to adjust its optical properties depending on monomers and on the number of quantum dots.
On the image on the left, the transparent unit from the polymer under normal conditions (large scale = 1 cm), and on the right of the same unit in the ultraviolet light. On the inset from above shows CT inside the matrix (large-scale scale insert = 50 nm).
According to scientists, with the help of functionalized CT, it will be possible to improve the quality of the image of flat and touch screens of mobile devices and televisions, as well as reduce energy consumption, while making them tensile and stronger.
