The photoluminescence (PL) of silver-decorated zinc oxide (ZnO/Ag) nanocolloids synthesized by picosecond laser ablation in water was studied. Compared to ZnO, a significant enhancement of the broad near-ultraviolet PL luminescence peak is observed in the presence of Ag nanoparticles (NPs), as well as changes in the broad multi-component visible emission feature. The comparative discussion of the...
Nanocrystalline ZnO thin films were grown by means of pulsed laser deposition. The ablation process was carried out at relatively low background oxygen gas pressure (10 Pa) and by varying the substrate temperature up to 600 °C. Information on the structural and morphological properties of the deposited thin films have been obtained by means of X-ray photoelectron, Raman spectroscopies, X-ray diffraction...
