Sažetak
In fields such as sensing, catalysis, and optoelectronics, it is crucial to find a way to design and fabricate nanocomposites based on semiconducting oxides with improved functional performances. In this context, SnO2 is interesting material, as it is an earth-abundant and widely used semiconductor with a bandgap of 3.6 eV and is known as a part of the transparent conductive oxide (TCO) family used in solar cells. The raw materials required for SnO2 are affordable, thus fostering continuous interest in exploring synthetic routes to SnO2 nanocrystals and nanostructures, including flame pyrolysis, thermal evaporation, hydrothermal synthesis, and various sol-gel methods. In this work, we report on a novel synthesis approach and combination of different methods to characterize SnO2 nanoparticles and nanostructured thin-films in order to control size and morphology through variation of reaction conditions. The samples prepared in the form of bulk and films with diverse morphology were thoroughly (micro)structurally characterized using X-ray diffraction along with AFM and SEM. In view of the potential application of prepared films as a layer in solar cells, the electrical characterization was carried out using Solid-State Impedance Spectroscopy (SS-IS) in a wide range of temperatures and frequencies. The obtained results show a high degree of chemical and structural homogeneity, see Fig. 1. An attempt was made to elucidate the processes behind the formation and growth of nanostructures as a function of the reaction settings. Moreover, the correlation between the (micro)structure and electrical features of prepared materials is discussed in detail. We seek to better control the SnO2 surface properties, including thin-film quality and homogeneity to facilitate charge transfer and mitigate recombination.
