The origin of the ArF excimer laser induced luminescence from a WF6/H2/Ar gas mixture was investigated. The experiments prove that the emission originates from excited W clusters with a size of about 10-20 nm. The influence of the H2 and Ar concentrations, the laser fluence and the repetition rate on the light intensity was studied.
