摘要： 本文采用蒸发溶液法从磷酸溶液中生长了KTbP4O12和一系列KLa1-xTbxP4O12晶体。讨论了晶体生长中的物理化学问题。测定了晶体的X射线衍射图和红外光谱,发现KTbP4O12晶体存在着α和β两种不同的结构类型。计算了不同结构类型晶体的晶胞参数。 测定了晶体的荧光光谱,观察到在KLa1-xTbxP4O12晶体中随着La3+离子浓度的变化而有规律的变化。观察到KTbP4O12能发出强的绿色荧光,将可能作为一种新的晶体发光或激光材料。
Abstract: KTbP4O12 and aseries of KLa1-xTbxP4O12 crystals were grown from phosphoric acid by evaporation solution method. The experimental conditions of erystal growth were discussed. The crystal structures of KTbP4O12 were measured by x-ray and infrared spe-ctra. It was found that there exist two types of structure, i. e. α and β structure. The fluorescent spectra of KTbP4O12 and KLa1-xTbxP4O12 were determined, the former emits strong green fluorescence and may be used as a new laser or luminescence material.
