Measurement of sputtered Mg particles in a plasma display panel discharge using laser induced fluorescence technique

Spatiotemporal distribution of Mg particles emitted from an MgO surface during an alternating current (ac) plasma display panel (PDP) discharge was directly measured using the laser induced fluorescence (LIF) technique. The results showed the existence of floating Mg particles intermittently emitted during short-lived PDP discharges. A spatial profile at 2 mm above the MgO surface had a peak at around the inner edge region of the electrode, which was resultant from the diffusion process of the intermittently emitted Mg particles mainly from the inner edge region.
