Abstract

Metastable BiBO₃ and rare-earth (RE)-doped RE_xBi _1-xBO₃ crystals were prepared through the crystallization of 50Bi₂O₃·50B₂O₃ and xRE₂O₃·(50-x)Bi₂O ₃·50B₂O₃ glasses (RE = Y, La, Gd, Yb), and their second harmonic (SH) intensities were examined using the Kurtz powder method. It was confirmed that BiBO₃ has two different crystalline forms, i.e., BiBO₃(I) and BiBO₃(II), and that BiBO ₃(I) transforms into BiBO₃(II) at temperatures around 500°C. Both phases were found to be nonlinear optical crystals with a phase matchable character, and the SH intensity of BiBO₃(II) powders was approximately 110 times as large as α-quartz powders. The incorporation of RE³⁺ into BiBO₃(II) was confirmed from X-ray diffraction analysis, and in particular, Gd_xBi_1-xBO₃(II) showed an enhanced SH intensity of approximately 145 times as large as α-quartz.
