UV LUMINESCENCE OF NED IN SOLID NEON-DEUTERIUM MIXTURES

Abstract Solid samples of neon-deuterium mixtures were irradiated by keV electrons, and the luminescence was measured between 100 and 300 nm. For concentrations between 0.1% D 2 in Ne and 1% Ne in D 2 an intense emission band was observed. The maximum intensity was observed for 10% D 2 in Ne. Comparisons with results from gas phase measurements indicate that the dominant component of the band originates from a bound-free transition from the A 2 Σ + state of NeD to the repulsive ground state.
