| 摘 要： | 利用水热合成法，在B掺杂p型金刚石膜上生长Eu掺杂ZnO纳米棒(Eu doped zinc oxide nanorods, ZnO:Eu NRs)，并研究其形貌变化、发光及半导体异质结电学特性等与Eu掺杂浓度的关系。结果表明：随Eu掺杂浓度的增加，ZnO:Eu NRs出现尖端聚集现象。Eu掺杂提高了ZnO纳米棒紫外发光强度。制作ZnO:Eu NRs/p型金刚石异质结，其表现出良好的整流特性，并可能出现微分负阻现象。 |

| Abstract： | In this paper, by hydrothermal method, the Eu doped zinc oxide nanorods (ZnO: Eu NRs) have been fabricated on p-type B-doped diamond films. The morphology, ultraviolet photoluminescence (UV-PL) and heterojunction electrical characteristic of the ZnO: Eu NRs are investigated. With increasing the doping level of Eu, a phenomenon of top aggregation emerges for the ZnO: Eu NRs, and the intensity of the UV-PL emission is enhanced. For the current-voltage measurements of the constructed ZnO: Eu NRs/p-diamond heterojunctions, a rectifying behavior is presented, and a possible negative differential resistance characteristic in the forward voltage is observed. |
