摘要：

Pressure induced spectral changes of the sigma (4.16 eV), pi (3.3 eV) and Ex (3.0 eV) luminescence bands in KI have been observed at 78 K. As hydrostatic pressure is increased, the peak energies of the three luminescence bands shift remarkably to higher energy, and the band widths become narrow. Furthermore, the intensities of the a and pi 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.
