概要
- 論文の詳細を見る
In a single crystal of KI/Tl, emissions from Tl^+ ion and a certain impurity were observed under excitation of light in the first characteristic absorption band of KI. These exciton-induced luminescences were measured at various temperatures for specimens of several concentrations of Tl^+ ion. The intensities of the exciton-induced luminescences attained saturated values at about liquid oxygen temperature. In consideration of the amount of energy transferred to the impurity, the saturated intensities of the exciton-induced luminescence from Tl^+ ion are almost independent of the concentration of Tl^+ ion in the range of 10^<15>〜10^<19>/cm^3 and showed a quantum efficiency as high as 30%. Therefore the migration of an exciton through the crystal was confirmed.
