Double Mode Emitting from a Novel Organic Microcavity Diode
The organic microcavity light emitting diode was fabricated using structure Glass/DBR/ITO/NPB/NPB:Alq/Al. Here NPB and Alq were mixed as the emitting material. In order to compare its performances with those of conventional MOLEDs,a heterostructure MOLED was also fabricated. There are many differences between the spectrum of the original microcavity light emitting diode and the conventional one. The voltage barrier was eliminated by mixing hole transport material and emitting material,thus recombination efficiency was enhanced and double modes emitting were realized and their FWHM (full width half maximum) were 8 nm and 12 nm respectively. White light emission from organic microcavity can be realized by optimizing the device structure and adopting new materials.
