摘　　要：Bright blue polymer light-emitting diodes have been fabricated by using the poly(pphenylenevinylene)-based copolymers with 10 C long aliphatic chains as the electroluminescent layers,PBD in PMMA and Alq_(3) as the electron-transporting layers,and aluminum as the cathode.The multilayer structure devices show 190cd/m^(2) light-emitting brightness at 460nm,15 V turn-on vol-tage.It is found that the intensities of photoluminescence and electroluminescence(EL)increase with increasing aliphatic chain length,the EL intensity and operation stability of these polymer light-emitting diodes can be improved by reasonable design of the structure.
