摘要
本文通过实验测量了Ｓｒ０．６３Ｂａ０．３７Ｎｂ２Ｏ６晶体吸收边光谱；由透射率曲线计算了吸收系数；并通过对α１／２—ｈν曲线特征的研究，肯定了３．５ｅＶ以下吸收边的间接跃迁性质；确定了声子的能量Ｅｐ与禁带宽度Ｅｇ。
In this paper,the station of the absorption edge of Sr 0 63 Ba 0 37 Nb 2O 6 single Crystal is measured with experimental studies.The absorption coefficient is calculated with transimitting curve.The absorption edge below 3 5eV is attributable to indirect transition by studing the α 1/2 hν curve.The phonon energy E p and the energy gap E g are ascertained.
