当地时间10月7日下午,瑞典皇家科学院宣布,将2014年诺贝尔物理学奖联合授予日本科学家赤崎勇、天野浩以及任教于美国加州大学圣巴巴拉分校的美籍日裔科学家中村修二,以表彰他们在发明一种新型高效节能光源方面的贡献,即蓝色发光二极管(LED)。半导体发光的节能效果甚为明显,LED真正发光层只有几纳米到十几纳米厚,在这么薄的材料里能量损失是极为有限的,因此可以达到显著的节能效果。
On the afternoon of October 7, local time, the Royal Swedish Academy of Sciences announced that it will jointly award the 2014 Nobel Prize in Physics to Japanese scientists Akasaki Akihiro, Akihiro Amano and the Japanese-American scientist Kenji Nakamura who taught at the University of California, Santa Barbara In recognition of their contribution in the development of a new energy-efficient light source, the blue light-emitting diode (LED). Energy-saving effect of the semiconductor light is very obvious, LED real light-emitting layer is only a few nanometers to ten nanometers thick, in such a thin material energy loss is extremely limited, so you can achieve significant energy savings.
