  <dc:description xml:lang="srp">U ovoj doktorskoj disertaciji prikazana je temeljna studija modifikovanja strukturnih, morfoloških i optičkih svojstava anatas TiO2 nanočestica dopiranjem trovalentnim jonima retkih zemalja: prazeodijuma, neodijuma, samarijuma, europijuma, disprozijuma, terbijuma, holmijuma, erbijuma i tulijuma, pri koncentraciji od 1 at.%. Pomenuti materijali sintetisani su sol-gel tehnikom i žareni na temperaturi od 420 ºC. Strukturna svojstva nedopiranog anatas TiO2 kao i TiO2 dopiranоg jonima retkih zemalja ispitivana su rendgenskom difrakcionom analizom. Utvrđeno je da se sol-gel sintezom dobijaju čiste anatasne kristalne strukture sa veličinom kristalita od svega nekoliko nanometara. Uticaj jona retkih zemalja u anatasnoj kristalnoj strukturi titan-dioksida ogleda se u značajnom porastu specifične površine čestica. Takođe, sintetisani su nanoprahovi TiO2 koloidnom tehnikom u cilju korelisanja različitih metoda sinteza sa strukturnim, morfološkim i optičkim svojstvima...</dc:description>
  <dc:description xml:lang="eng">The primary aim of this thesis is to explain the modification of structure, morphology and optical properties of anatase TiO2 nanoparticles doped with trivalent rare-earth ions: praseodymium, neodymium, samarium, europium, terbium, dysprosium, holmium, erbium, and thulium, with the concentration of 1 at.%. These materials were synthesized by the sol-gel technique and further annealed at 420 °C. Structural properties of anatase TiO2 and TiO2 doped with trivalent rare-earth ions are studied by X-ray diffraction analysis. It was confirmed that pure anatase TiO2 with the crystallite size of only a few nanometers was obtained by sol-gel synthesis. The incorporation of rare earth ions in the anatase TiO2 is reflected in the significant increase of the specific surface area of TiO2 nanopowders doped with rare-earth ions in comparison with undoped TiO2. Also, the TiO2 nanopowders were synthesized by a colloid technique to correlate the different methods of synthesis with structural, morphological and optical properties...</dc:description>
