    Abstract: Organic light emitting devices (OLEDs) are provided that include two red emissive dopants. The two dopants may be disposed within a common organic emissive layer in an OLED, or each may be disposed in a separate layer. Configurations including multiple layers having multiple dopants are also provided, in which a first red dopant is disposed in a separate organic layer from a second red dopant, and a common dopant of another color, such as green, is disposed in each organic layer. Devices as disclosed herein are capable of providing an R9 value of at least 80, and of providing white light with a CRI of at least 80.
