High performance OLED that includes deuterated compounds in the emissive layer are disclosed. The OLED includes an anode; a cathode; and an emissive layer, disposed between the anode and the cathode. In the OLED, the emissive layer includes a first phosphorescent emitter and a first host; the first phosphorescent emitter is a metal complex; the first host is partially or fully deuterated; and at least one additional condition is true.

Organic electroluminescent materials and devices

Provided are novel compounds having a structure of that are useful as emitters in OLEDs.

A compound having the following formula is disclosed. The compound is useful as an emitter in OLED applications.

A metallic article for high temperature applications such as a turbine engine component is protected by a thermal barrier coating system on the article's metallic substrate. The thermal barrier coating system includes a bond coat layer of aluminum containing alloy on the metal substrate, an alumina layer on the bond coat layer and a ceramic thermal barrier layer on the alumina layer. The bond coat layer is doped with elemental barium that enhances the creep resistance of the alumina layer, thus, minimizing spallation of the ceramic thermal barrier layer.
