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φ19mm×65mm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（0.65-16μm）和吸收系数较低（〈0.3cm-1）。
As growing e-GaSe single crystal, volatile component and curving solidification interface spoil the qualities of crystals. The GaSe single crystal in φ19mm×65mm 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.
