Luminescence of rare gas crystals at high excitation densities for VUV laser applications

Exciton luminescence in krypton cryocrystals with an admixture of molecular deuterium

“…This kind of exciton interaction yields a single electron-hole pair, the subsequent relaxation and recombination of which produces a single localized or free exciton. It should be noted that this sort of "quenching" of intrinsic luminescence has been observed previously in cryocrystals of pure inert elements under pulsed irradiation by 600 keV electrons 15 and was interpreted in terms of collisions among electronic excitations in the irradiated samples.…”

“…with atoms and molecules of inert matrices, in particular krypton. [10][11][12][13][14][15] This paper is an experimental study of the cathodoluminescence of pure krypton and of the binary and ternary alloys Kr-D 2 , Kr-D 2 -O 2 , and Kr-Xe-O 2 over a wide range of impurity concentrations. It has been found that introducing deuterium impurity into krypton leads to a significant (by more than a factor of five) increase in the intrinsic luminescence of the matrix.…”

Interaction of heavy ion beams with dense plasmas

“…The scintillator is placed at the distance of the focal plane of the fine focusing system to check the actual focal size. The method for growing rare gas crystals is adopted from Nahme and Schwentner (1990). A Plexiglas (PMMA) box (growing chamber) is pressed against a sample holder made of aluminum.…”

VUV Laser Spectroscopy of Trivalent Rare-Earth Ions in Wide Band Gap Fluoride Crystals

“…Strong dipole transitions between the bound electronic excited state and the dissociative ground state of diatomic clusters of Xe 2 , Kr 2 , and Ar 2 in liquid, gas, or solid phase [36][37][38][39] provided a new powerful radiation source in the VUV. These systems were characterized by high quantum efficiency in the emitted wavelength, high gain, and conversion efficiency.…”
