Cheap, flexible,white light

摘要

Silver nanowires offer a way to solve two problems facing those making light- emitting diodes (LEDs). LEDs tend to be made from inorganic materials. Those based on organic materials are thinner, lighter weight, cheaper to make and more easily spread over large, flexible surfaces. But the white light that they produce is not the same at all angles, and current organic LEDs are hampered by stiff electrodes. These are not compatible with flexible manufacturing and are made of indium tin oxide, an increasingly scarce material.
