Process for forming an organic light-emitting diode luminaires having a single light-emitting layer with at least two light-emitting dopants

1. A process for making an OLED luminaire, comprising:

providing a substrate having a first electrode thereon;

depositing a first liquid composition comprising a small molecule host material, a first light-emitting material as a first dopant having a first emitted color, and a second light-emitting material as a second dopant having a second emitted color, all in a first liquid medium, wherein the first dopant is a blue dopant selected from a chrysene derivative having arylamino substituents, the second emitted color is selected from a red dopant and a yellow dopant, and the ratio of first dopant to second dopant is 20:1 to 40:1; and wherein the yellow dopant is selected from the group consisting of rubrenes, naphthacenes, and fluoranthenes and wherein the red dopant is a red dopant which is a cyclometalated Ir complex having phenylquinoline or phenylisoquinoline ligands;

forming a second electrode overall;

wherein the overall emission color of the luminaire is white.

2. The process of claim 1 , wherein the first electrode is patterned and the light-emitting layer is deposited in a pixellated pattern.

3. The process of claim 1 , wherein the light-emitting layer further comprises a third light-emitting material as a third dopant having a third emitted color, wherein the first dopant is a blue dopant, the second dopant is a yellow dopant, and the third dopant is a red dopant; and wherein the ratio of blue dopant:(yellow dopant+red dopant) is 20:1 to 40:1.

4. The process of claim 3 , wherein the ratio of yellow dopant:red dopant is in the range of 10:1 to 1:10.

5. The process of claim 1 , wherein the liquid medium is a polar solvent selected from the group consisting of C 1 to C 20 alcohols, ethers, and acid esters.

6. The process of claim 1 , wherein the liquid medium is a non-polar solvent selected from the group consisting of C 1 to C 12 alkanes, toluene, xylenes, and trifluorotoluene.

7. The process of claim 1 , wherein the liquid medium is selected from the group consisting of methylene chloride, chloroform, chlorobenzene a substituted or non-substituted toluene or xylene, tetrahydrofuran N-methylpyrrolidone an ester ethylacetate, isopropanol, cyclopentatone, and any mixture thereof.

8. The process of claim 1 , which further comprises deposition of a chemical containment layer to define pixel areas.

9. The process of claim 1 , wherein the small molecule host material is selected from a material having the formula:

An-L-An

where:

An is an anthracene moiety;

L is a divalent connecting group;

and a material having the formula:

A-An-A

where:

An is an anthracene moiety;

A is the same or different at each occurrence and is an aromatic group.
