Optical properties for N,N-bis (lnaphyhly)- N,N-diphenyl-1,1-biphenyl-4,4-diamine and tris (8-hydroxyquinolinato) aluminum in organic light emitting devices.

The optical properties of N,N’-bis (Inaphthyl)-N,N’diphenyl 1,1’-biphenyl-4,4’-diamine (NPB) and tris (8-hydroxyquinolinato) aluminum (Alq3)organic materials used as hole transport and electron transport layers in organic light-emitting devices (OLED) have been investigated. The NPB and Alq3 layers...
