Abstract: An organic light emitting device having an anode; an emissive region; and a cathode is provided. The emissive region can be disposed between the anode and the cathode. The emissive region can include a first compound, D1, which is a first metal complex; and a second compound, D2, which is a second metal complex, where D1 and D2 are different. The emission from the OLED does not primarily originate from D2 or from an exciplex between D1 and D2, the emission from the OLED has an emission peak maximum between 300 to 2000 nm; and, when the emission from the OLED has a peak between 550 and 700 nm, then D2 is not a Be, Al, or Ir complex. Consumer products containing the OLED are also provided.
