扫描电镜X射线能谱分析法测定低能重离子注入黄豆种子的深度
THE DEPTH OF LOW ENERGY HEAVY IONS Fe~+,Cu~+ AND Zn~+ INTO SOYBEAN SEEDS DETECTED BY SEM-EDAX
【摘要】 利用200kV 离子注入机产生的 Fe~+、Cu~+和 Zn~+3种重离子分别对黄豆种子进行直流注入,以扫描电镜X射线能谱分析法测定低能重离子的注入深度。测量定结果表明,Fe~+的最大注入深度未超过18μm,Cu~+、Zn~+的最大注入深度可达25μm。
【Abstract】 The soybean seeds were implanted with Fe~+,Cu~+ and Zn~+ low energy ions which were pro- duced by 200kV implantation ion installation at Institute of Modern Physics,Lanzhou.The im- plantation depth of ions was determined by means of a scanning energy dispersive analysis of X- ray(SEM-EDAX).The analysis results showed that the depth of Fe~+ ions implantation was not more than 18 μm,the deepest depth of Cu~+ and Zn~+ ions implantation reached was 25μm.
