本文应用原子吸收分光光度计、电子探针及UV-265紫外可见分光光度计等测试手段,对氟化钡晶体在退火过程中外界杂质离子的扩散效应进行初步的探讨。退火时用杂质含量较高的氟化钡多晶料做固定氟化钡晶体的填充物,在真空条件下经1100℃退火6小时后,原来无色透明的氟化钡晶体表面呈现深粉红色,在垂直于圆柱体的横断面上显色度不同的同心状
In this paper, atomic absorption spectrophotometer, electron probe and UV-265 UV-Vis spectrophotometer were used to test the diffusion effect of external impurity ions during the annealing of barium fluoride crystals. Annealing with a higher impurity content of barium fluoride polycrystalline barium fluoride fixed filler, annealed at 1100 ℃ under vacuum for 6 hours, the original colorless and transparent barium fluoride crystal surface presents a dark pink , In the cross-section perpendicular to the cylinder with different color concentric
