"Revolutionary Material Enables Customizable Light Blocking for Windows"

Researchers have developed a material for dynamic windows that can switch between three modes: transparent, blocking infrared light to keep buildings cool, and tinted windows to control glare. By injecting lithium ions and electrons into tungsten oxide hydrate, the material can selectively block targeted wavelengths of light. The presence of water in the crystalline structure allows for more resistance to deformation, resulting in two modes: a "cool" mode that absorbs infrared light and a "dark" mode that blocks both visible and infrared light. This discovery may accelerate the development of commercial products with enhanced features and inspire innovation in energy storage and conversion materials.
