ZnO nanomaterials with controlled size, shape and surface chemistry are required for applications in diverse areas, such as optoelectronics, photocatalysis, biomedicine and so on. Here, we report on ZnO nanostructures with rod-like and spherical shapes prepared via laser ablation in liquid using a laser with millisecond-long pulses. By changing laser parameters (such as pulse width and peak power), the size or aspect ratio of such nanostructures could be tuned. The surface chemistry and defects of the products were also strongly affected by applied laser conditions. The preparation of different structures is explained by the intense heating of liquid media caused by millisecond-long pulses and secondary irradiation of already-formed nanostructures.

“…11 The control of its properties is primarily in the context of novel applications as highly efficient gas sensing material 12,13 and photocatalysis. 14,15 For this reason, a better understanding of the synthesis of microstructures with different morphologies is important and necessary to achieve objectives and applications on materials for the modern world. A protable, simple and easily scalable method to synthesize the material is the microwave chemical bath deposition (MWCBD).…”

“…PL emission spectra have been widely used to understand the migration, transfer, and recombination of photo-induced electron-hole pairs in semiconductors [24,31,32]. The role of the CNTs in the photocatalytic activity was explored by collecting the PL spectra of the SnO 2 nanoparticles and SnO 2 -CNTs, respectively.…”
