摘要： 在研究熔剂法生长NAB[NdAl3(BO3)4]晶体时,发现存在一种组份为BaO·Nd2O3·Al2O3·6B2O3的新晶体.晶体呈片状,浅紫色,具六方对称性.晶胞参数a=4.566(2)Å,c=24.93(1)Å.本文描述了它的生长条件及其结晶学研究.在聚敛偏光下观察到它的一轴晶干涉图,测出它为正光性晶体,并在室温下测绘了它的荧光光谱.

Abstract: We have found a new crystal whose composition is BaO·Nd2O3·Al2O3·6B2O3 while studying the miorolaser crystal NAB[NdAl3 (BOs) 4]. The crystal is in sheet shape and is light purple. It possesses hexogonal symmetry. The unit cell parameters are a=4.566 (2) Å, c=24.93 (1) Å. This paper describes its growth conditions and crystallographio study. Under convergent polarized light, the interference pattern of its uniaxial crystal was observed, and the crystal was determined to be positive light crystal. Fluorescence spectrum was also measured at room temperature
