AB  - U ovom radu ispitivana je mogućnost primene nanočestica ZnO za fotokatalitičku degradaciju boje bromkrezol zeleno i komercijalno dostupne boje za bojenje tekstila. Vodena suspenzija nanočestica ZnO dobijena je laserskom ablacijom [1]. Koncentracija nanočestica određena je metodom ISP-OES. Rastvori boje sa različitim količinama nanočestica izlagani su dejstvu UVC zračenja i to u intervalima od 5 minuta u ukupnom trajanju od sat vremena. Degradacija boja u toku ozračivanja utvrđena je merenjem apsorbancije UV-VIS spektrometrijom pre, tokom i nakon ozračivanja. Preliminarni rezultati potvrdili su početnu pretpostavku da se nanočestice dobijene laserskom sintezom mogu koristiti za degradaciju boja.
AB  - In this paper, the possible use of ZnO nanoparticles for photocatalytic degradation of dyes, in particular bromocresol green and commercial textile dyes, was examined. А water suspension of ZnO nanoparticles was prepared by laser ablation. Concentration of nanoparticles was measured by ICP-OES technique. Dyes solutions with different amounts of nanoparticles were exposed to UVC irradiation at 5 minute intervals for a total period of 1 hour. Degradation of dyes during irradiation was determined by UV-VIS spectroscopy by measuring solution absorbance before, during, and after exposition. Preliminary results confirmed the initial assumption that laser synthesized nanoparticles could be used for dye degradation.

AB  - The bicomponent nano particles draw attention of the researchers because introducing the second component into the crystal lattice of the nanoparticle we can tune physical properties of the material. One of the simplest and fastest method for synthesis of various bicomponent nanoparticles is by pulsed lasers ablation of the bulk material in water. For the synthesis of our bicomponent nanoparticles we use twostep process. The first step is to deposit a thin film of metal onto ZnO substrate using pulsed laser deposition in vacuum (PLD). The second step is to produce colloidal solution of nanoparticles by laser ablation in water (LAL) of metal coated ZnO. The ablating target was then scanned with laser beam in order to avoid heating of the target and to produce the high yield of bicomponent nanoparticles. The obtained nanoparticles were characterized using UV-VIS, XPS, SEM and XRD diagnostics. The second process that we used for synthetizing bicomponent zinc oxide nanoparticles was self-propagating room temperature reaction of zinc nitrate with sodium hydroxide with addition of (x=1; 3 and 5%) of AgNO3. The chemical composition of the produced nanoparticles is Zn1−xAgxO (x=0.01;0.05 and 0.05). After the reaction, obtained powder was calcinated at 1100 °C for 4 h in a furnace. The diffraction patterns were recorded at room temperature and atmospheric pressure in the absence of any re-heating of the samples. From the XRD spectra we found that no second phase were formed in the samples, the ions of silver are embedded into the crystal lattice of the nanoparticles. The bicomponent nanoparticles produced with these two methods are tested for the photocatalytic activity. We used UV lamp for irradiation of nanoparticle and organic dye (methylene blue – MB) mixture in a cuvette. The nanoparticles synthetized with both methods show good photocatalytic activity for degradation of organic dye.
