Abstract:For the first time we have demonstrated hybrid silicon organic light emitting diodes. This process uses particles created in a nonthermal silane plasma which are treated by photo oxidation to passivate the surface. Particles were mixed into several conducting organic matrices. Strong emissionw was seen for the NPs in PVK, with the NPs emitting at the expected wavelegth. The NP emission increased with current density, with the matrix emission becoming negligible at the highest power. The mechanisms for current conduction and energy transfer were studied and point out the importance of the exciton energy transfer process for hybrid devices.
