摘要: 当生长ε相的硒化镓单晶时, 组分挥发和固液界面震荡严重损坏晶体的结晶质量。利用改进垂直布里奇曼法生长出Φ19 mm×65 mm硒化镓单晶。X射线粉末衍射仪(XRD)和傅立叶红外光谱仪(FT-IR)分别用于测量晶体的结晶度和光学性质。红外测试表明, 硒化镓晶体透过波谱较宽(0.65~16 μm)和吸收系数较低(<0.3 cm-1)。

Abstract: As growing ε-GaSe single crystal, volatile component and curving solidification interface spoil the qualities of crystals. The GaSe single crystal in Φ19 mm×65 mm size was grown by modified vertical Bridgman method. The crystallinity and optical properties of as-grown crystals were measured by XRD and transmission spectra, respectively. The FT-IR measurements indicated wide transparency over the spectral range (0.65-16 μm) and low absorption coefficient (<0.3 cm-1) in grown GaSe crystal.

Key words: Bridgman technique, nonlinear optical crystal, solidification interface
