I only have hard copy SID journals as a references but by just doing a quick search on google you can find many articles (some more accurate than others) on the topic.
While not totally accurate the following describes the AC addressing:http://www.hdtvmagazine.com/articles...iew_plasma.php

This jibes with AC plasma theory of ops articles that indicate that the time it takes for the UV output of ionized gases used in PDP's to decay after being pulsed is also on the order of tens of microseconds.
From my earlier posts you can easily back calculate the individual sustain pulse length assuming 4-6ms emmision time.
6000us / 256 ~ 23us per sustain pulse for 8bit
6000us/ 1024 ~ 6us per sustain pulse for 10bit
But, like I said before, this has nothing to do with decay of the phosphor. The rise and fall time for each sustain "INTERVAL" is what matters. Each interval contains many sustain pulses.
In my opinion there are three possibilites that may cause color fringing or trailing or flashing in Plasma displays:
1 - Dynamic false contouring [a motion artifact that plasma suffers from]
2 - Non linear PWM
3 - Color fringing caused by sub-pixel control
