Abstract

Some NiO-doped Bi₂O₃,La₂O₃-SrO-BaO-Nb₂O₅-B₂O₃ glasses giving the formation of strontium barium niobate Sr_0.5Ba_0.5Nb₂O₆ (SBN) crystals with a tetragonal tungsten-bronze structure through conventional crystallization in an electric furnace have been developed, and SBN crystal lines have been patterned on the glass surface by heat-assisted (250-300 °C) laser irradiation and scanning of continuous-wave Nd:YAG laser (wavelength: 1064 nm). The surface morphology and the quality of SBN crystal lines are examined from measurements of confocal scanning laser micrographs and polarized micro-Raman scattering spectra. The surface morphology of SBN crystal lines changes from periodic bump structures to homogeneous structures, depending on laser scanning conditions. It is suggested that the line patterned at the laser irradiation condition of laser power P=1 W and of laser scanning speed S=1 μm/s in 2NiO-4La₂O₃-16SrO-16BaO-32Nb₂O₅-30B₂O₃ glass has a possibility of the orientation of SBN crystals along the laser scanning direction. The present study demonstrates that the transition metal atom heat processing (i.e., a combination of cw Nd:YAG laser and Ni²⁺ ions) is a novel technique for spatially selected crystallization of SBN crystals in glass.
