【摘要】 本文是在用Bridgman法生长二氧化碲(TeO2)晶体前提下,运用光学显微镜、电子衍射光谱、化学腐蚀等方法分析了该方法生长TeO2晶体内部的缺陷。初步讨论了散射点、微裂纹、气泡和黑点、条纹以及腐蚀坑等微缺陷的形成机理。并就如何减少这些微缺陷进行了初步探讨。
【Abstract】 Paratellurite (TeO2) crystals were grown by Bridgman method. Optical microscopy, electronic diffraction spectrum, and chemical etching were used to investigate the crystal defects. The formation mechanism of different defects such as scattered-point, cleavage, bubble and black inclusion, striation and etch pit was discussed. Some suggestions to decrease the defects were put forward.
