2014年10月7日,瑞典皇家科学院宣布,将本年度的诺贝尔物理学奖授予日本科学家赤崎勇、天野浩和美籍日裔科学家中村修二,以表彰他们发明新型节能光源蓝色发光二极管(LED).LED是一种发光二极管,是一种能够直接将电能转化为可见光的固态半导体器件.1927年,一向致力于研究半导体的俄国人奥列格·罗塞夫发现了第一个LED,但这个发现在当时却并没有找到任何商业应用.到了1955年,在美国无线 On October 7, 2014, the Royal Swedish Academy of Sciences announced that it will award this year’s Nobel Prize in Physics to Japanese scientists Akasaki Akira, Uchino Amano and Japanese-American scientist Nakamura Shuji in recognition of their invention of a new energy-saving light source blue light-emitting diode (LED) .LED is a light-emitting diode, is a kind of solid-state semiconductor devices that can directly convert electrical energy into visible light.In 1927, Russia has always been committed to the study of the Russian Oleg Rousseff found the first LED, but this Found that at the time did not find any commercial applications. By 1955, wireless in the United States
