High Performance Ultraviolet Photodetector Fabricated with ZnO Nanoparticles-graphene Hybrid Structures被引量:1
《Chinese Journal of Chemical Physics》2013年第2期225-230,I0004,共7页刘金养 于欣欣 张光辉 吴昱昆 张琨 潘楠 王晓平 
This work is supported by MOST of China (No.2011CB921403), the Chinese Academy of Science, and the National Natural Science Foundation of China (No.10874165, No.90921013, No.11074231, and No. 11004179).
Ultraviolet (UV) photodetector constructed by ZnO material has attracted intense research and commercial interest. However, its photoresistivity and photoresonse are still unsatisfied. Herein, we report a novel meth...

Ga掺杂对ZnO纳米结构可见光发射的抑制效应被引量:2
《物理学报》2012年第16期410-415,共6页沈庆鹤 高志伟 丁怀义 张光辉 潘楠 王晓平 
国家重点基础研究发展计划(批准号:2011CB921403)资助的课题~~
采用碳热还原反应和原位掺杂的方法制备了不同Ga掺杂浓度的ZnO纳米结构.X射线衍射显示掺杂纳米结构中为单一的氧化锌纤锌矿结构.扫描电子显微镜观测发现随掺杂浓度的增大,纳米结构的形貌逐渐从纳米六棱柱变为纳米锥.光致发光和X射线光...
