  报道了金刚石薄膜的蓝区电致发光现象，总结了几种有关金刚石薄膜蓝区发光“A”带的发光机理。

原声例句

• Absorption is just the opposite of emission, so instead of starting at a high energy level and dropping down, when we absorb light we start low and we absorb energy to bring ourselves up to an n final that's higher.
  吸收就是发射的逆过程,与从一个高能量到低能量不同，当吸收光时，我们从低能量开始,吸收能量到一个更高的能量。

专业释义

物理学

• 光发射

  However, a-SiN_x films are regarded as ideal candidates for the study of PL in silicon-based compound due to its wide gap (about 5.3eV), strong light emission and lower barriers for electrons and holes than silicon oxide.
  尽管如此,由于氮化硅是一种宽带隙半导体(带隙约为5.3eV),具有较强的光发射,并且比二氧化硅窄的带隙更有利于载流子注入,所以非晶SiN_x薄膜已经成为了研究硅基复合物发光的理想候选材料。
