摘要: 2014年诺贝尔物理学奖授予为开发GaN基高亮度蓝光发光二极管(LED)而做出先驱性工作的三位科学家。作者在阐释了这三位科学家的获奖理由以及蓝光LED对人类社会的重要意义后,简要回顾了获奖人在上世纪80年代至90年代针对蓝光LED这一技术难题,从技术路线的选择,到关键技术瓶颈的突破,再到最后取得成功所做的艰苦卓绝的工作。最后,作者还讨论了蓝光LED在带动产业发展和学科发展上的重要意义。Abstract: The Nobel Prize in Physics of 2014 was awarded to the three scientists who did the pioneering work for development of high-brightness GaN-based blue light-emitting di-odes (LEDs). In this article, the award-winning grounds of the three scientists and the signifi-cance of blue LED on human society were interpreted firstly. Then, it was reviewed briefly that the arduous work did by the winners in the 1980s-1990s to develop the blue LED, including ini-tial technical route selection, the breakthroughs of key technical bottlenecks, and the final suc-cess. Last, the significance of the blue LED to drive development of industry and academy were also discussed.
