Recently, there are some reports that show the high efficacy in the ultraviolet generation form the plasma display panels(PDP). One of the factors allowing such high efficacy is the pulse width to be very short. However, the mechanism how the short pulsed discharges are related with the high efficacy is not clear. This study aims to clarify the mechanism based on the measurements of basic parameters such as electron density and electron temperature of short pulsed discharges. Measurements were performed for the dielectric discharge simulating the PDP discharge and a capacity coupled discharge(CCD). It was confirmed that the short pulsed discharges for both realized improvements in the ultraviolet generation, ant possible causes for that are discussed.
