Nanophotonic radiative decay rate engineering for stable, phosphorescent emission of blue light
The radiative and non-radiative decay rate of phosphorescent emitting materials can be tuned by the geometry of the nanostructure (NP).Invention Summary: Blue-emitting, phosphorescent organic light emitting diodes (OLEDs) have high efficiency but low stability. As a result, the less efficient fluorescent materials are typically used in OLEDs to ext...
