摘　　要：利用Te熔剂方法,在天宫二号飞船上成功地生长了ZnTe:Cu晶体.微重力下生长的晶体质量优于地面生长的晶体,相同实验条件下,天宫二号上生长的晶体尺寸明显大于地面尺寸.通过阴极荧光光谱(CL)无损检测技术测试了5 kV、15 kV、25 kV高压下的ZnTe:Cu晶体的阴极荧光图谱及光谱.ZnTe：Cu crystals were successfully prepared on TG-II spacecraft by Te solvent Method. The quality of crystal growing in the microgravity is much better than those growing on the ground at the same experiment conditions. The size of crystals prepared on TG-II is larger than those prepared on the ground. Cathodoluminescence was used to measure ZnTe：Cu crystals at 5 kV、15 kV,25 kV voltages. CL mapping and spectra were conducted at different voltages. It was found the crystals growing in mi- crogravity possess lower density of defects.
