Abstract

This paper describes a facile sacrifical (NH4)0.5V2O5 nanowires approach to single-crystalline NdVO4 nanorods. The nanorods have a rectangular cross section of about 30 x 30 nm2 to 100 x 200 nm2, and length ranging from 400 to 700 nm. Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) show that the nanorods grew respectively along the [312] and [101] direction on the (NH4)0.5V2O5 nanowires. Ultraviolet (362 nm) and blue (467 nm) emissions can be observed under excitation of 310 nm at room temperature, suggesting that the nanorods should be good candidates for fabricating UV and blue nanodevices.

摘要

本文描述了一种通过牺牲性（NH4）0.5V2O5纳米线制备单晶NdVO4纳米棒的简便方法。这些纳米棒具有约30×30nm2至100×200nm2的矩形横截面，长度在400至700nm之间。透射电子显微镜（TEM）和选区电子衍射（SAED）表明，纳米棒分别沿（NH4）0.5V2O5纳米线上的[312]和[101]方向生长。在室温下，310nm激发下可观察到紫外（362nm）和蓝光（467nm）发射，这表明这些纳米棒有望成为制造紫外和蓝光纳米器件的良好候选材料。
