Lasers comprising a substrate and a layer of organic material over the substrate. The organic material includes host and dopant materials that result in the laser emission of a desired color when pumped by optical pump energy. Host materials include CBP and tris-(8-hydroxyquinoline) aluminum, which when combined with dopant materials such as coumarin-47, coumarin-30, perylene, rhodamine-6G, DCM, DCM2, and pyrromethane-546 result in the efficient lasing of colors such as blue, green and yellow. |
