摘要：

Excitation spectra of the activator luminescence directly excited by UV light and creation spectra of the photostimulated luminescence are investigated for KBr-In crystals with different In+ concentrations. It is shown that the electronic states responsible for these two kinds of luminescence differ. Careful analysis of the excitation spectra allow us to find a new D-absorption band having Gaussian shape with the following parameters: peak position at E0 = 6.375 eV and halfwidth DELTAE = 0.14 eV. The oscillator strength f = 0.12 of the D-band is also determined.
