Abstract: By placing an switching layer between the both light emitting layers, we have achieved the change of electroluminescence spectra from polymer and dye complex films with driven DC voltage. It was found that there are two bands with peak wavelength 455 nm and 520 nm in ELspectra which origined respectively from dye TPBand Alq, and the relative intensity of emission at 455 nm increases with the driven DCvoltage increasing. From the analysis of energy level of materials used, it can be found that there were both potential barrier in PVK/PBD and PBD/Alq interface, and the carriers transferring both potentials barriers at the driven voltage have some difference which made the combination of carriers shift their position when the driven voltage varied. This first discovery provides a new approach for full colour display in device fabrication.
