2024年3月21日,中国科学院合肥物质院安光所张庆礼研究员课题组与健康所江海河研究员课题组在梯度浓度激光晶体生长及激光性能研究方面进一步深入合作,采用类泡生方法生长了不同梯度浓度的Nd:YAG和Nd:GdYAG激光晶体,Nd:GdYAG的激光性能优于近似梯度浓度Nd:YAG晶体,相关研究成果以《渐变浓度掺钕钇铝石榴石系列晶体的生长与激光性能》为题发表在国际知名光学TOP期刊Optics and ...
采用射频磁控溅射技术在Si(111)衬底上制备了未掺杂ZnO薄膜和Nd及其与Fe,Mn共掺杂ZnO薄膜.通过XRD分析表明,未掺杂ZnO薄膜沿c轴择优生长,掺杂ZnO薄膜偏离了正常生长,薄膜为纳米多晶结构.应用AFM观测所有薄膜的表面形貌,掺杂使ZnO薄膜表面粗糙.室温光致发光谱显示,薄膜出现了395?nm的强紫光和495?nm的弱绿光带.Nd掺杂ZnO薄膜的PL谱线峰值强度减弱,Nd与Fe...
