Abstract: The bilayer devices using a mixture film of triplet emitting material Cu4(C≡CPh4)4L2[L=1,8 bis(diphenyl phosphino)-3,6-dioxaoctane](Cu4) and hole transport polymer poly(9-vinylcarbazole)(PVK) as emitting layer, electron transport material TAZas the electron transport layer were prepared. Different devices that formed by varied Cu4 ratios show different light emitting properties through singlet-triplet and triplet triplet-energy transfer. The result showed a new application of triplet emitting materials.
