贝尔实验室的研究人员发明一种纯净的铱膜,用电脉冲激发,马上变为深蓝色。膜的颜色可以保持若干小时,并施加一个反极性的脉冲而把颜色除去。此种铱膜可能代替发光二极管和液晶显示。这种电致变色材料显示可用于手表和计算器。铱化合物显示所消耗的功率比发光二极管少,也不
Researchers at Bell Labs invented a pure iridium film that was excited by an electrical pulse and immediately turned dark blue. The color of the film can be maintained for several hours and a reverse polarity pulse is applied to remove the color. This iridium film may replace light-emitting diodes and liquid crystal display. This electrochromic material is shown for use in watches and calculators. Iridium compounds show less power than light-emitting diodes, nor do they
