We demonstrate light emission with two distinct peaks: a spectrally narrow blue emission from monomers and a yellow broadband emission created close to the interface of the organic film and SiO2. Due to the functionality of Mg/Au stacked electrodes, we are able to position the recombination zone via gate voltage control. Therefore, we are able to shift the spectral peak position and change the emission intensity independently by the drain voltage. The emission color is tunable from CIE coordinates (0.27, 0.28) to (0.40, 0.41). © 2009 American Institute of Physics. |
