چکیده انگلیسی
The study of two different methods to obtain Strontium Barium Niobate nanocrystals has been carried out. Previously, Nd2O3 doped SrO-BaO-Nb2O5-B2O3 glasses were fabricated using the melt quenching process. In the first method, a thermal treatment in an electrical furnace at 620 °C was used to obtain glass ceramic samples. In the second one, the nanocrystals were obtained under continuous Ar laser irradiation in a localized zone in the glass sample. The X-ray diffraction patterns confirmed the formation of SBN nanocrystals in both cases. The optical measurements indicate the incorporation of Nd3+ ions into the nanocrystals which produces an increment of the luminescence intensity. Moreover, a calibration with the temperature has been carried out for the ratio of the Nd3+ emissions. This result could let to control the temperature of the laser irradiated zone.
