摘　　要：不同 EDTA(乙二胺四乙酸 )掺杂浓度条件下生长了 KDP(磷酸二氢钾 )晶体 ,超显微法观察了 ED-TA对 KDP晶体光散射性质的影响。结果表明 ,随着溶液中 EDTA含量的增加 ,相应晶体内部的光散射现象加重。其原因在于当溶液中 EDTA含量较高时 ,阻碍了 KDP晶体的生长 ,导致了液相包裹物的产生 ,造成光散射 ;同时发现 ,同一晶体不同部分的光散射也不同。对 EDTA的影响机理进行了初步的探讨。KDP crystals with different concentration of EDTA in solution were grown; light scatter was detected with laser scanning technique. It was proved that light scatter in KDP crystal was aggravated with the increasing concentration of EDTA in growth solution for EDTA inhibited the growth of KDP crystal at high concentration, thus mother liquid inclusions were formed, which cause light scatter. And the light scatter in KDP varied within different sector of KDP crystal. The effect mechanism was discussed.
