The growth mechanism and PL performance of Bat-Eike ZnO Nanorods

摘要

Bat-like ZnO nanorods were prepared by evaporation of Zn powders without any catalyst. The length of nanorods ranged from several micrometers to tens of micrometers. Growth mechanism of the nanorods was discussed combining field emission scanning electron microscopy and high-resolution transmission electron microscopy results. The photoluminescence spectrum was measured by using a He-Cd laser as the excitation source (325 nm) and all the results indicated the product had perfect crystal quality.
