Electroluminescent Devices Based on Triplet Materials Cu4 Doped PVK and Special Increasing Emitting Mechanism

Abstract

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.

Key words: Triplet, Electroluminescence, Photoluminescence, Transitional metal complex
