摘要: 激光显微拉曼光谱对KDP晶体包裹体研究发现,相邻锥扇界附近的球形溶液包裹体串只有水溶液,而柱面扩展包藏和含高密度散射颗粒的KDP晶体都存在CO2和H2S等杂质分子.我们推断,柱、锥面包裹体成分的不同与晶体不同面的生长特征有关,CO2等杂质气体分子的存在是柱面包裹体和散射颗粒形成的原因之一.

Abstract: The inclusions in KDP crystals were studied by using laser microscope Raman spectrum technique. Water solution
was found in the spherical inclusions between pyramid sectors, while CO2 and H2S in the prolate inclusions in expanded prismatic sectors besides
water solutions. These impurities were also found in the crystals with dense scatters. The results show that the compositions differences in above inclusions
are related to different growth mechanisms on the prismatic and the pyramidal faces of the crystal. The existence of these impurities in growing solution
is one of the factors to generate the inclusions as well as scatters in crystals.

Key words: scatter, inclusion, KDP crystal, Raman spectrum
