Effects of Hydrostatic Pressure on the Self-Trapped Exciton Luminescence in KI
スポンサーリンク
概要
- 論文の詳細を見る
Pressure induced spectral changes of the σ(4.16 eV), π(3.3 eV) and Ex (3.0 eV) Luminescence bands in KI have been observed at 78 K. As hydrostatic pressure is in-creased, the peak energies of the three luminescence bands shift remarkably to higher energy, and the band widths become narrow. Furthermore, the intensities of the σ and π bands decrease gradually, and that of the Ex band increases slightly. These results are discussed on the basis of a Rabin-Klick ratio and an exciton-phonon coupling strength, depending on hydrostatic pressure.
