Hierarchical tree-shaped nanostructures, nanobelts, and nanowires of Zn3P2 were synthesized in a thermal assisted laser ablation process. All nanostructures are tetragonal phased Zn3P2 with excellent crystallinity and are free from an oxidization layer according to electron microscopy and X-ray diffraction analyses. Optical measurement revealed a strong absorption from the ultraviolet to near-infrared regions. Optoelectronic devices fabricated using individual nanowires demonstrate a high sensitivity and rapid response to impinging light. A crossed heterojunction of an n-type ZnO nanowire and a p-type Zn3P2 nanowire has been characterized, and it offers a great potential for a high efficient spatial resolved photon detector.
通过热辅助激光烧蚀工艺合成了Zn3P2的分层树形纳米结构、纳米带和纳米线。根据电子显微镜和X射线衍射分析，所有纳米结构均为具有优异结晶度的四方相Zn3P2，且没有氧化层。光学测量显示从紫外到近红外区域有强烈吸收。使用单个纳米线制造的光电器件对入射光表现出高灵敏度和快速响应。对n型ZnO纳米线和p型Zn3P2纳米线的交叉异质结进行了表征，它为高效空间分辨光子探测器提供了巨大潜力。
