德国科学家最近开发出一种新技术 ,通过电场精确控制可以使半导体纳米晶体显示出不同的色彩 ,进而制造出新型有机发光二极管 ,并为制造可弯曲的显示屏提供了可能。半导体纳米晶体通常尺寸只有几个纳米。研究发现 ,半导体纳米晶体粒度的差异可以导致其呈现不同的色彩 ,是制造有 Recently, German scientists have developed a new technology that enables the semiconductor nanocrystals to display different colors through precise control of the electric field, thereby creating a new type of organic light-emitting diode and making it possible to manufacture a flexible display. Semiconductor nanocrystals are usually only a few nanometers in size. The study found that the differences in grain size of semiconductor nanocrystals can lead to their different colors,
