“…Significantly, ZnO can be easily grown in a variety of bespoke nanostructures [2,4,5] which typically provide different but controllable optical and mechanical properties when compared with their bulk counterparts. Consequently, bulk and nanostructured ZnO, in particular ZnO nanorods (NRs), can be used in a broad range of practical electronic devices, such as LEDs, laser diodes, photovoltaics, photodetectors and chemical sensors [6][7][8][9][10][11][12][13][14]. However, many applications require precise control over the dimensions of the ZnO NRs.…”

Low-temperature hydrothermal growth has emerged as a popular method for the fabrication of ZnO nanorods (NRs), increasing the functionality and utility of ZnO-based devices. In this work, we study the influence of growth time, temperature and seed layer on the dimensions and angular distribution of ZnO NRs. High-quality NRs with a crisscrossed 60° angular distribution have been grown with a 20–60 nm diameter and 600 nm length. We show that, within the ideal range of growth parameters, the growth time and temperature have no controllable influence on NR diameter and length, while the deposition method and size of the pre-growth deposited ZnO seeds affects diameter and NR angular alignment. We demonstrate advantages of using crisscross-aligned NRs over planar ZnO for the enhancement of ZnO excitonic emission by optical coupling with gold nanoparticles. These results can be readily adapted for applications that involve surface coating-mediated enhancement of both light emission and injection. Graphical abstract

While this goal can be achieved by a number of different growth techniques, [15][16][17][18] most of these approaches are expensive and often di cult to scale up.…”

Low-temperature hydrothermal growth has emerged as a popular method for the fabrication of ZnO nanorods (NRs), increasing the functionality and utility of ZnO-based devices. In this work, we study the influence of growth time, temperature and seed layer on the dimensions and angular distribution of hydrothermally grown ZnO NRs. High-quality ZnO NRs with a crisscrossed 60° angular distribution with respect to the substrate normal have been grown with a small diameter (20–60 nm) and a length of approximately 600 nm. We show that, within the ideal range of growth parameters (70–100°C for 2–4 hours), the growth time and temperature have no controllable influence on diameter and length, while the deposition method and size of the pre-growth deposited ZnO seeds affects diameter and NR angular alignment. Control over both is important for device structures involving wave-guided, angular dependent light emission and for high sensitivity and speed of chemical sensors. Furthermore, we demonstrate advantages of using crisscross-aligned ZnO NRs over planar ZnO for the enhancement of ZnO excitonic emission by optical coupling with gold nanoparticles (NPs). These results can be readily adapted for various applications that involve surface (NP) coating-mediated enhancement of both light emission or injection.
