According to media reports, researchers from the Department of Physics and Analytical Chemistry of the University of Jaime I in Spain participated in a design project for semiconductor nanosheets. This series of nanosheets has a wider range of colors and can improve the quality of LCD displays and LED screens. performance.
Juan Ignacio Climente, professor of physical chemistry, explained that so far, the semiconductor structure of optical devices has provided strong and pure purple and green, but the other color properties provided are lacking. This innovative research has further expanded the best performance of yellow, orange and red light. At the same time, significant progress has been made in the development of semiconductor materials for optical devices, allowing LED and LCD displays to have major breakthroughs in the display industry.
Specifically, Climente said: “We have performed mechanical quantitative calculations, and the results show that the new colors emitted are emitted by nanosheets with a larger thickness synthesized by our partners. This also provides us with information about these materials. New insights into its unique optical properties. The new synthesis method can extend the traditional thickness (3.5-5.5 layers of atoms) to 8.5 layers.”
Semiconductor nanosheets are intended for use in second-generation quantum dot displays, which can provide purer and deeper colors than current LCD or LED screen technologies. In addition, these nanotechnology materials can also be used in laser devices and optical sensors.
The quantum chemistry group of the prestigious School of Technology and Experimental Science specializes in theoretical research on nanocrystals. Researchers from this group use quantum mechanics tools to model these systems to understand and predict their physical properties. Recently, the team proved that the new semiconductor nanosheets synthesized in the laboratory can improve the luminosity of LED displays, lasers, and LCD display screens of computers or televisions. Compared with existing semiconductor materials, such nanosheets can maximize the luminosity. Minimize energy loss.
