Luminescence of the uranyl-ion-doped elpasolite lattice

Journal of Physics: Condensed Matter, 2000
Distinct species U(III), U(IV), U(V) and U(VI) have been identified when U(VI) or U(IV) species are doped into the cubic elpasolite lattice. The band intensities, and derived vibrational frequencies, in the luminescence and absorption spectra of the uranyl ion situated in this lattice are compared with those of Cs2UO2Cl4.

Scintillation and anomalous emission in elpasolite Cs2LiLuCl6:Ce3+

Journal of Luminescence, 2006
Abstract The luminescence and scintillation properties of Cs 2 LiLuCl 6 :0.5%Ce 3+ are presented. Special attention is devoted to a 9.4 ns fast emission at 275 nm that can only be excited via the highest cubic field 5d e state of Ce. Contrary to Cs 3 LuCl 6 and Cs 2 LiYCl 6 , where the same type of fast emission was observed, the emission in Cs 2 ...

Two-photon (TP) spectroscopy of terbium(III) elpasolites

Journal of Luminescence, 1995
Data from the single-colour polarised TP spectra and emission spectra of crystals of Cs2NaTbCI6 and Cs2NaTbF6, and from the emission spectrum of Cs2NaTbBr6 have been analysed. Evidence is found for a large correlation crystal field, in several multiplets, that cannot be attributed to spin-correlation alone.

Unit cell group analysis of rare earth elpasolites

Vibrational Spectroscopy, 2003
Abstract Vibrational frequencies of rare earth elpasolites, with general formula M 2 ALnX 6 (M=Cs, Rb; A=K, Na, Li; Ln=lanthanide element or yttrium; X=I, Br, Cl, F) have been determined from Raman spectroscopy and electronic absorption and emission spectra, at temperatures down to 10 K. A compilation has been made together with available literature

19F NMR Studies of Rare Earth Elpasolites

1979
19F NMR studies were made on cubic elpasolites containing rare earth ions Pr3+, Tb3+, Ho3+ and Er3+. The anisotropic shift tensor in each case was significantly larger (∼20%) than that predicted by the direct dipole interaction.

Neutron-Gamma Discrimination in Elpasolite Scintillator Detector

2016
Existing nuclear stockpiles and weapons-making capabilities imperil the global community. Current nonproliferation efforts involve the research and development of newer, more efficient detection systems that can be deployed for the interdiction and monitoring of special nuclear materials (SNM).
