据《科学时报》报道,美国科学家研究出一种刺激微小纳米晶体发光的新方法,该方法可用于制造亮度更高、能耗更低、寿命更长的显示设备、交通信号灯和室内照明灯等。利用半导体材料制造的发光二极管寿命很长,能耗只有普通灯炮的五分之一,已经应用 According to the Science Times, U.S. scientists have developed a new method to stimulate the luminescence of tiny nanocrystals that can be used to make display devices with higher brightness, lower energy consumption and longer lifetimes, traffic lights and interior lights, etc. . The use of semiconductor materials, light-emitting diodes have a long life expectancy, energy consumption is only one-fifth of ordinary light bulbs, has been applied
