Metal atom (Zn, Cd and Mg) luminescence in solid neon

Luminescence spectroscopy of the metal atoms Mg, Zn and Cd isolated in solid neon is recorded using pulsed synchrotron radiation excitation of the ns¹ np¹ ¹P₁–ns² ¹S₀ resonance (n = 3, 4 and 5 respectively) transitions. Two features, a dominant band and a red-shoulder, are identified in the UV abs...
