Abstract:
1. An organic light emitting device comprising: a substrate; an anode formed on a surface of the substrate; a fluorescent polymer light emitting layer formed on a surface of the anode and comprising a fluorescent visible light emitting material and a phosphorescent dopant emitting in the infrared portion of the spectrum, the phosphorescent dopant being selected from Pt-tetraphenyltetrabenzoporphyrin, and Pt-tetraphenyltetranaphtho[2,3]porphyrin; and a cathode formed on a surface of the fluorescent polymer light emitting layer, wherein the fluorescent polymer light emitting layer is doped with the phosphorescent dopant in a range of about 0.1 to about 3.0 wt % with respect to a total weight of the fluorescent light emitting material, wherein, when the organic light emitting device is operated, an emission amount of the phosphorescent dopant is equal to or less than 1/10 of an emission amount of the fluorescent visible light emitting material.
