Abstract
Photoluminescent(PL) spectra of Alq3 as supplied and after thermal tre atment was measured to verify the degradation during thermal imidizati on of poly(amic acid). The electroluminescent devices(ELDs) composed o f ITO, Alq3/BPDA-PDA PAA or BPDA-PDA polyimide, Mg, and In were fabric ated. Current-voltage and EL characteristics of the ELDs were also stu died. At 50/50 composition, the turn-on voltage of ELD was ca. 12V. Th e ELD illuminated bright green light at 25V.
