A thin film electroluminescence cell with the structure of ITO/PPV/PVK: Eu(TTA)4C5H5NC16H33: PBD/Alq3/Al has been fabricated. Red emission with a very sharp spectral band at 614nm was observed and a maximumluminance of 20cd @ m-2 at 36V was obtained from the spin-coated device. The full width at half maximum of luminescent spectrum is less than 10nm.
