Abstract

Ovaj rad bavi se istraživanjem priprave tankih filmova titanijevog dioksida (TiO₂) pomoću tehnike nanošenja ablacije iskrom. Titanijev dioksid odlikuju odlična fotokatalitička, kemijska i optička svojstava, zbog čega se široko koristi u područjima fotokatalize, zaštite okoliša i pretvorbe energije. Tehnika ablacije iskrom nudi prednosti u odnosu na druge metode zbog svoje brzine, efikasnosti i ekološke prihvatljivosti. U ovom radu analizirat će se utjecaj parametara ablacije na strukturu, morfologiju i optička svojstva TiO₂ filmova. Za detaljnu analizu korištene su metode kao što su rendgenska difrakcija pri okrznujućem upadnom kutu (engl. grazing incidence X-ray diffraction, GIXRD) za istraživanje kristalne strukture, mikroskopija atomskih sila (engl. atomic force microscopy, AFM) i pretražna elektronska mikroskopija (engl. scanning electron microscopy, SEM) za ispitivanje površinske morfologije, te difuzna refleksijska spektroskopija (engl. diffuse reflectance spectroscopy, DRS) za analizu optičkih svojstava filmova. Rezultati istraživanja pružit će uvid u kvalitetu filmova dobivenih ovom tehnikom i njihovu primjenjivost u različitim područjima.

Abstract (english)

This thesis focuses on the investigation of the preparation of thin titanium dioxide (TiO₂) films using the spark ablation technique. Titanium dioxide is characterized by excellent photocatalytic, chemical, and optical properties, which is why it is widely used in the fields of photocatalysis, environmental protection, and energy conversion. The spark ablation technique offers advantages over other methods due to its speed, efficiency, and environmental friendliness. In this work, the effect of ablation parameters on the structure, morphology, and optical properties of TiO₂ films will be analysed. Methods such as grazing incidence X-ray diffraction (GIXRD) for studying the crystal structure, atomic force microscopy (AFM) and scanning electron microscopy (SEM) for examining surface morphology, and diffuse reflectance spectroscopy (DRS) for analysing the optical properties of the films were used for detailed analysis. The results of the research will provide insight into the quality of the films produced by this technique and their applicability in various fields.
