Characterization and Photoluminescence Properties of AluminaNanowires Elaborated by Arc-Plasma

C.Arnoult , X.Devaux , H.Rinnert , M.Vergnat

Ultrafine powders containing alumina nanowires are synthesized by DC arc plasma from pure aluminium metal. Nanowires grow only when reactive gases are composed of nitrogen and less than ten percent of oxygen. Nanowires have the diameters ranging from 20 to 80 nm and lengths ranging from hundreds nan...

材料科学技术（英文）

Ordered ZnO nanowire arrays embedded in anodic aluminum oxide (AAO) membranes were fabricated by electrochemical deposition of Zn(NO3)2+H3BO3 solution in a boiling bath. Scanning electron microscope (SEM) and transmission electron microscope (TEM) observation results show that the polycrystalline Zn...

新型炭材料

以Si粉、SiO2粉和人造石墨为原料，在1480℃、4 kW、80 min的真空微波辐照条件下快速高效地合成SiC纳米线。利用SEM、TEM、XRD等对所得产物的微观结构解析表明，在未使用催化剂的条件下，基于气固( VS)机制可成功制备出β型SiC。根据坩埚中的部位不同，所得SiC呈现出不同的形貌。...
