用化学气相输运方法成功地合成了三元Zn2GeO4纳米线及其分支结构。纳米线为三方晶相，沿[110]方向生长占优势。由于同质外延生长，枝条呈现出与主干垂直的择优生长方向。用气相−-液-固−机理解释了以Au为催化剂的纳米线生长过程。这种催化生长方法可以更好地控制Zn2GeO4纳米线的形貌和结构，促进对其性能和应用的进一步研究。
Ternary Zn2GeO4 nanowires and their branched structures were successfully synthesized by a chemical vapor transport method. The nanowires showed a rhombohedral crystal phase with dominant growth direction along [110]. The branches exhibited preferential growth directions, which are perpendicular to the backbone due to homoepitaxial growth. The nanowire growth process was explained using vapor−liquid−solid mechanism with Au as catalysts. The present catalytic growth method may offer better control of the morphologies and structures of the Zn2GeO4 nanowires, promoting further study of their properties and applications.
