Investigation of the High EFFiciency Luminescence of RE(Er)and Oxygen (O) Double Implanted GaAs and Si

Abstract

用光致发光谱(Pl)、傅里叶变换红外吸收话(fTIr)和X射线衍射谱(Xrd)等研究了稀土(Er)和氧(O)双离子注入gAAS和SI的发光特性和高效发光机理。Pl测量结果发现:(Er和O)双注入样品对比Er单注入样品的发光(Pl)强度(Er的1.54μM峰)显著增大,发光单色性等也有明显改善。测量并分析了该材料的fTIr和Xrd谱;对该材料的高效发光机制作了较深入地探讨和澄清。The RE(Er) and oxygen(O) double ion-implanted GaAs and Si are studied by using PL.FTIR and XRD.The PL measurement results show that the luminescent intensity (Er 1.54 μm peak) of (Er, O) double implanted samples is much stronger than that of single Er-implanted samples and the monochromaticity of luminescence is improved.The FTIR and XRD of the materials are measured and analyzed.The mechanism of the high eFFicienct luminescence of the materiaIs is investigated deeply.国家自然科学基金;南京大学团体微结构实验室资
