Light-emitting device with organic layer doped with photoluminescent material
A light-emitting device includes an anode, a cathode, and at least one organic electroluminescent (&#8220;EL&#8221;) material positioned between the anode and the cathode. Nanoparticles of at least one photoluminescent material are dispersed in the organic EL material. The organic EL material emits a first electromagnetic (&#8220;EM&#8221;) radiation having a first spectrum in response to an applied electrical field. The PL material absorbs a portion of the first EM radiation emitted by the organic EL material and emits a second EM radiation having a second spectrum. A plurality of the light-emitting devices are arranged on a transparent substrate to provide a panel display or a lighting source.
