【摘要】 应用在国产DX-3A扫描电镜上自己研制的阴极射线致发光装置,研究了La₂Ti₂O₇,晶体生长缺陷。观察到包裹物、生长条纹、带状缺陷等。配合能量色散谱,吸收光谱、X射线荧光光谱和偏光显微术等方法,探讨了所观察到的缺陷发光机制,并对生长缺陷的形成机理作了简单的分析。更多还原

【Abstract】 The as-grown defects in La₂Ti₂O₇ crystals, such as precipitates, growth striation, "band-like" defects etc. were studied by means of cathodoluminescence detector system designed andmanufactured in our laboratory for DX-3A SEM （China）. The luminescence of defects wasinvestigated combined with energy-dispersive x-ray spectrometry, optical absorption spectrome-try, energy-dispersive x-ray fluorescence spectrometry and optical microscopy. The formationmechanism of these as-grown defects was briefly discussed.更多还原
