Abstract

Nanotehnologija ima izuzetno svijetlu budućnost jer nudi precizno oblikovanje materijala na najfinijoj razini. Nanostrukture cinkova oksida (ZnO) su od velike važnosti zbog jedinstvenih kemijskih, električkih i optičkih svojstava. Svoju primjenu pronalaze u brojnim naprednim tehnologijama, a istraživanja nanostruktura cinkova oksida su usmjerena na optimizaciju metoda sinteze kako bi se u potpunosti iskoristio njihov potencijal. Cilj rada bio je usporediti dva pristupa priprave predložaka za rast tankih filmova nanostrukturiranoga ZnO.
Za pripravu početnih slojeva upotrijebile su se metoda ablacije iskrom i metoda oblaganja rotiranjem, dok se za daljni rast nanoštapića na svim uzorcima upotrijebila kemijska metoda taloženja iz otopine. Nakon sinteze, uzorci su karakterizirani pomoću rendgenske difrakcijske analize (engl. X-ray diffraction, XRD) i mikroskopije atomskih sila (engl. Atomic force microscopy, AFM).

Abstract (english)

Nanotechnology holds a remarkably bright future, offering the ability to precisely manipulate materials at the finest scale. Zinc oxide (ZnO) nanostructures are of great importance due to their unique chemical, electrical, and optical properties. These nanostructures are utilized in a wide range of advanced technologies, while research on zinc oxide nanostructures aims to optimize synthesis methods to maximize their potential. The aim of the study was to compare two approaches to preparing templates for the growth of thin films of nanostructured ZnO. Seedlayers were prepared using the spark ablation method and the spin coating method, while the chemical bath deposition method was used for the subsequent growth of nanorods on all samples. After synthesis, the samples were characterized using X-ray diffraction (XRD) analysis and atomic force microscopy (AFM).
