Growth of CeO2:Bi12SiO20 Crystals in Multi-Position Furnace(Ⅱ)- Space Growth Experiment

Abstract

Abstract: Ce-doped Bi₁₂SiO₂₀ single crystal with size of φ10mm×40mm was successfully grown in space on board of the spacecraft Shenzhou No.3. The surface morphology of space-grown crystal is different from that of ground-grown crystal.The space- and ground-grown crystals were measured by X-ray rocking curves, absorption spectra and micro-Raman spectra. The results show that the quality of Ce-doped crystal grown in space is better than that of the ground-grown one. The effect of doping on optical properties of BSO grown in space is evient in comparison with the ground-grown crystal.

Key words: doped cerium bismuth silicon oxides （Ce:BSO）, crystal growth, multi-position furnace, microgravity, Raman spectrum
