| 摘 要： | 采用第一性原理,对O与Er共掺杂硅纳米晶粒的电子结构及光学性质进行了计算.计算结果表明:O原子的掺杂没有影响Er掺硅纳米晶粒的禁带宽度；Er掺硅纳米晶粒结构在紫外区的吸收峰因O原子的掺入明显加强,红外区源于Er原子的吸收峰峰值减小.

| Abstract: | The electronic structure and optical properties of oxygen and Er-doped silicon nanoparticle were investigated by first-principles to provide the theory guidance for the silicon-based material’s development.The calculation results show that the doping of oxygen atom don’ t affect the bandgap of Er-doped silicon nanoparticle;the absorption peak at ultraviolet region enhance obviously and the absorption peak rooted up Er atom decrease for the doping of oxygen. |
