“…(c) show the vibration difference between the glass and irradiated glass, which indicates the structural change from amorphous to ordered units during irradiation. Furthermore, the bending or stretching vibrations in irradiated glass are assigned to polycrystalline Bi 2 ZnB 2 O 7 accurately . Consequently, these results demonstrate the Bi 2 ZnB 2 O 7 crystals are precipitated in glass by fs laser irradiation.…”

We report on the formation of Bi2ZnB2O7 crystal structures with designated patterns in ZnO–Bi2O3–B2O3 glass by femtosecond laser direct writing. The crystallization mechanism in glass is investigated by crystallization kinetics analysis and simulation of the three‐dimensional temperature field distribution. The crystallized regions show larger third‐order optical nonlinearity than the unirradiated region in glass by Z‐scan technique. This finding is of great potential in application of nonlinear optical integrated devices and development of new nonlinear materials.

“…The growth of LBGO crystalline fibers was performed with the μ‐PD technique using the resistive apparatus installed in our laboratory . The LBGO powders were put into a platinum (10*5*3 mm 3 ) crucible fitted with a 2 mm in length cylindrical capillary (internal diameter: 1.2 mm, external diameter: 1.4 mm).…”

The LaBGeO 5 compound (LBGO) was prepared by solid state reaction at 1050°C and characterized by XRD and DTA analysis. The direct growth of LBGO fibers from the melt using micro-pulling down technique was unsuccessful because of its high viscosity. The study of the LBGO-LiF phase diagram showed that LiF could be considered as a convenient flux to reduce viscosity of the melt during the growth process. Several crystal fibers were then grown and characterized by Raman spectroscopy. To decrease the high volatility of LiF, B 2 O 3 was added to the melt. A white cloudy fiber was obtained from LiF-B 2 O 3 flux and checked by Raman spectroscopy and scanning electron microscopy.

“…The origin of the disordered parts was considered to be connected to the presence of a still unidentified Bi-rich phase produced by the reaction of the melt with the platinum crucible. The high viscosity of the melt would impede its total dispersion and dilution resulting in the formation of the colored amorphous zones [10]. The principal objective of this paper was to confirm or disprove these hypotheses and to define the growth conditions allowing the preparation of colorless BZBO single crystal fibers.To this end, BZBO fibers were grown by two techniques: the micro-pulling down method (-PD) and the laser heated pedestal growth technique (LHPG).…”

Bi 2 ZnB 2 O 7 (BZBO) fibers grown by the micro-pulling down technique (-PD) usually present a more or less pronounced color ranging from yellow to red and a microstructure showing glassy clear parts (more concentrated in bismuth) dispersed in a darker matrix. In a previous paper, we assumed a reaction between the platinum crucible and the melt to explain both their color and microstructure. To confirm or invalidate this hypothesis, BZBO fibers were pulled under different conditions by the -PD or laser heated pedestal growth(LHPG) techniques. Various physical characterizations methods such as: SEM, EDS microprobe, Raman micro-spectroscopy, DTA and X-ray diffraction were performed to evaluate their crystal quality. Finally, it appears that the origin of the observed features of the fibers grown lies in the evaporation of a substantial amount of boron oxidefrom the melt. This leads to a shift of its composition in the ZnO-B 2 O 3 -Bi 2 O 3 ternary system andan incongruent melting behavior. Therefore, the obtainment of colorless and transparent fibers requires very low pulling rates.
