Examines the effect of doping and conversion time on the photoluminescence (PL) of p-phenylene vinylene (ppv) based light emitting devices. Impact of sulfuric acid treatment and lithium doping of ppv films on PL peaks; Range of PL peaks in unconverted and partially converted materials; Reason for the shift of PL peak from green to blue.
