“…For this purpose we have studied the power dependence of nonlinear absorption in rare gas crystals and we present emission spectra of Xe, ICr, Ar crystals. Liquid rare gases have been investigated in a similar way by the group of Rhodes et al [3], and charge carrier generation by two-photon absorption in solid Xe has been reported in [4].…”

The power dependence up to the destruction limit and the coefficient of two photon absorption in Xe and K r crystals are derived from transmission and luminescence experiments. A temperature dependent reduction of the quantum efficiency for luminescence a t high power densities due to exciton-exciton annihilation is observed.Die Intensitatsabhangigkeit und der Koeffizient fur Zwei-Photonenabsorption werden fur Xeund Kr-Kristalle aus Transmissions-und Lumineszenzexperimenten bestimmt. Die Lumineszenzquantenausbeute ist bei hohen Intensitaten tempcraturabhangig und wird durch Exziton-ExzitonAnnihilation reduziert.

“…The XeKr exciplex emission arising from the decay of the lowest excited molecular states, l(3Pz) and O+(3P1), to the repulsive part of the O+('So) state was reported by several authors. Most of these studies were performed using nonselective excitation on solid [4-81 or liquid samples [8,9] of Kr doped with various Xe concentrations. Consequently, the emission of the exciplex could not clearly be separated from that of the Xez and Krz excimers.…”

Time- and Energy-Resolved Luminescence of the XeKr Exciplex

The emission spectrum of the XeKr exciplex was recorded by selectively exciting the first atomic resonance of xenon doped into liquid and solid krypton. A single emission band, centred at 7.87 eV, was observed in the liquid. In the solid the emission spectrum is time dependent. For longer times (t25 ns) after excitation it is almost identical to the one obtained in the liquid. At shorter times an additional band peaked at ∼ 8.30 eV is superimposed. For the first time, the radiative lifetime of the 1(3P2) exciplex could be determined. Its value is (52 ± 3) and (50 ± 3) ns in the liquid and the solid, respectively. The corresponding value for the dilute gas is estimated to be 140 ns.
