NettetLight-emitting diodes (LEDs) can be manufactured to emit light in the ultraviolet range, although practical LED arrays are very limited below 365 nm. LED efficiency at 365 nm is approx 5-8%, whereas efficiency at 395 nm is closer to 20%, and power outputs at these longer UV wavelengths are also better. forest \u0026 sandridge primary schoolNettet21. jan. 2015 · An ultraviolet (UV) transparent and stable methyl-siloxane hybrid material was prepared by a facile sol-gel method.
