The influence of high hydrostatic pressure on the emission bands and long wavelength excitation bands of the phosphors NaCl(Eu), KCl(Eu), KBr(Eu), and KI(Eu) was investigated. A pressure of 6000 atm led to a shift of 0.02 to 0.035 ev in the emission spectra of these phosphors toward a longer waveleugth. Phosphors conspicuous for the greatest compressibility also showed slight shifts of the excitation bands toward a longer wavelength. The results obtained indicate that the diminution of interionic distances in the phosphors investigated leads to the "compression" of the energy spectrum of luminescence centers. (auth)
