Nanowerk  June 26, 2024 Hybrid glasses derived from meltable metal-organic frameworks (MOFs) promise to combine the intriguing properties of MOFs with the universal processing ability of glasses. Researchers in Germany developed optical-quality glasses derived from the zeolitic imidazole framework which allowed them to perform in-depth studies of optical transparency and refraction across the ultraviolet to near-infrared spectral range. Using this fundamental data, they demonstrated the fabrication of micro-optical devices by thermal imprinting. They showed that concave as well as convex lens structures could be obtained at high precision by remelting the glass without trading-off on material quality. This enabled multifunctional […]
