Temporal evolution of optical emission spectra from alternating-current plasma display panel

Here is presented experiment on temporal evolution and spatial distribution of optical emission spectra from alternating-current plasma display panel (AC-PDP). Measurement shows that the relative emission intensity (I-Ne(585nm)/I-Xe(823nm)), which is induced from Ne and Xe atom, drastically changes in each discharge stage and each spatial region. In initial discharge, Intensity of Ne emission (I-Ne(585nm)) is much stronger than that of Xe emission (I-Xe(823nm)) in cathode and anode region, and I-Ne(585nm)/Xe(823nm) decreases with an increase in discharge time (t(d)). There is also considerable effect of discharge voltage (V-s) and gas pressure (P-Ne/Xe) on I-Ne(585nm)/Xe(823nm). The time-resolved measurement of optical emission spectra is useful to investigate the electron temperature (T-e) in PDP.
