硅纳米晶体的尺寸仅为几纳米,却具有很高的发光潜力。现在,来自德国卡尔斯鲁厄理工学院(KIT)和加拿大多伦多大学的科研人员借助硅纳米晶体,成功制造出了高效的硅基发光二极管(SiLEDs),其不含重金属,却能够发射出多种颜色的光。硅虽然在微电子和光伏产业占据着主导地位,但长期以来其却一直被认为不适合发光二极管的制造。然 Silicon nanocrystals are only a few nanometers in size, but have high light-emitting potential. Now researchers at KIT and the University of Toronto in Canada have succeeded in creating efficient silicon-based light-emitting diodes (SiLEDs) using silicon nanocrystals that contain no heavy metals and are capable of emitting a wide variety of Color light. Although silicon plays a dominant role in the microelectronics and photovoltaic industry, it has long been considered unsuitable for LED manufacturing. Of course
