Abstract

Organic light emitting diodes using Pt-based red, green and blue dopants have been built for application to solid state lighting. All layers were deposited by thermal evaporation. Devices used a stacked design with separate red, green and blue layers. Blue devices achieved external quantum efficiencies of over 16% while devices with red / green / blue emissive layers reached quantum efficiencies of up to 15%, depending on the thickness of the red and green layers. We demonstrate an all-Pt based multiple emissive layer WOLED device.
