摘    要:采用水热合成法制备了纯菱形相的Zn2GeO4纳米棒,研究了水热制备前驱体溶液的pH值对材料尺寸及形貌的影响以及Zn2GeO4纳米棒的光学性质。扫描电子显微镜(SEM)测试结果表明,随着前驱体溶液pH值的变化样品逐渐由微米级块状结构生长成为纳米颗粒,并且进一步形成纳米棒结构。纳米棒的尺寸由长200 nm变化到500 nm。室温光致发光(PL)光谱中观察到位于450和530 nm两个不同的发光峰,其分别源于Zn2GeO4的不同缺陷能级。

关 键 词:锗酸锌  纳米棒  水热合成法  发光特性

Abstract:Zn2GeO4 nanorods were synthesized through a facile hydrothermal method at different pH values, and the morphology and luminescence properties of Zn2GeO4 nanorods were systematically studied. The SEM results indicate that the particle sizes decreased with the increased in pH values from micro-to nano-size, and the length of Zn2GeO4 nanorods (L=200~500 nm) can be controlled through the pH values. Two emission bands centered at 450 and 530 nm were observed which are associated with different native defects in Zn2GeO4 nanocrystals.
Keywords:Zn2GeO4  nanorod  hydrothermal method  luminescence property
