  • Single crystals play quite an important role in material applications. In the process of single crystals growth, ingredients of crystals vary along its growth orientation because of the segregation. Consequently, uniformity of the crystal may be affected, which add to the disadvantage of its application. In order to study the influence of microgravity on the segregation of multicomponent crystal, the crystal growth through the platform of Tiangong-2 is planned. Considering the growth properties and the condition of Tiangong-2, Eu2+ doped CsI is chosen as the study object. The inner structure of quartz ampoule is designed, which passes the vibration experiment successfully. Moreover, the high quality single crystal is grown in the laboratory, and the concentration segregation is found obviously in the specimen.
