Alignment Behavior and Field Emission Properties of Cadmium Sulfide Nanowires Synthesized via a Bismuth Triiodide Sheet-Assisted Solution-Phase Method
摘要
Abstract
Ordered CdS nanostructures were synthesized under controlled conditions via a low-temperature solution- phase procedure. Bismuth triiodide (BiI3) sheets were selected because of their dissolvable, two-dimensional template which confines the growth ofCdS nanowires (NWs). By adjusting the BiI3 sheet size and reaction temperature, square grid planar CdS NW networks, woven CdS NW networks, and CdS NW arrays were synthesized. Transmission electron microscope analysis, X-ray diffiaction pattern, and photolumineseence (PL) test indicated that these nanostructures have a desirable crystalline structure. The field emission measurements of the square grid planar CdS NW networks, the woven CdS NW networks, and the CdS NW arrays revealed that the modification of the CdS NWs' alignment from horizontal to vertical resulted in the enhancement of their electron field emission properties.关键词
