摘要
采用传统降温法生长了一系列的K(H1-x Dx)2PO4晶体。粉末X射线衍射(XRD)证明氘化后晶体的对称性并没有发生改变,晶胞参数a随氘含量的增加而增大,参数c则小幅度增大。对晶体的高分辨X射线衍射研究,结果表明KDP-DKDP混晶中,D取代部分的H原子对晶体的结晶完整性影响较小。
A serials of K（H1-xDx）2PO4 crystals were grown by using traditional method from deuterated solu- tions. From the results of powder X-ray diffraction （XRD）, it shows that the no changes occurred on symmetry of structure in K（H1- xDx ）2PO4 crystals, while lattice parameter a increases with a increase of deuterium con- tent of crystal. High resolution XRD was taken to characterize crystalline perfection. It was indicated that crys- talline perfection was destroyed slightly by the replacement of partial H atoms by D atoms in KDP-DKDP mixed crystals.
