Abstract

Intense emission in the ultraviolet (250-400nm) from OH (A 2Σ+) and the rare gas-deuteride excimer ArD has been observed from mixtures of H2O vapour or D2 in Ar and excited in microcavity plasma devices. Peak wavelength-integrated intensities are measured for H2O and D2 concentrations of ∼0.16 and 0.5-1, respectively. Spectral simulations indicate the OH (A 2Σ+, v=0) rotational temperature to be 440±20K for 600 Torr Ar/0.3 Torr H2O mixtures excited in a 45nL microcavity.
