Abstract:
Novel devices comprising a layer including compounds that are capable of triplet triplet annihilation up conversion (TTA-UC). In particular, the up-conversion layer absorbs light emitted by the OLED device and emits up-converted light with shorter wavelength in response. These devices may be used to provide improved lifetime for blue emitting devices.
