概要
- 論文の詳細を見る
Optical spectra of KCl crystals heavily doped with Pb^<2+> ions are investigated at temperatures between liquid nitrogen temperature (LNT) and 600℃. Aggregates and precipitates are found in heavily doped samples. With the rise of temperature, the aggregates are decomposed at temperatures near 425℃ and the precipitates are formed near 400℃. The aggregates are different in type from the ones observed hitherto. The formation of the precipitates with the rise of temperature is observed. It is shown by this experiment that high-temperature absorption measurement is a powerful method for investigating the behavior of the heavily doped impurity.
