“…ZnO nanorod/nanowire structures can be used as foundation blocks in a variety of applications such as short-wavelength nanolasers [5,6], field-effect transistors [7], nanosized gas sensors [8][9][10], nanoresonators, UV sensors [11][12][13], nanocantilevers [14], blue electroluminescent devices [15], high heterojunction area solar cells [16][17][18], and field emitters [19]. ZnO nanorods/nanowires can be grown using a variety of methods such as chemical vapor deposition (CVD), thermal evaporation [20,21], electrodeposition [22,23], catalyst-free combust-oxidized mesh (CFCOM) [24], oxidizing in air Zn metal films [25], and chemical bath deposition (CBD) [26][27][28]. Among these methods, CBD is a flexible technique to synthesis ZnO nanostrucures with a powerfully controlling on their morphology.…”
