Abstract
A polarized light-emitting device is fabricated by a method that includes forming a radiation-emitting layer. The radiation-emitting layer includes a radiation-emitting material that emits radiation having a wavelength included in an emission wavelength band. The radiation-emitting material is disposed between a transparent anode and a transparent cathode. An optically active reflective layer is disposed on the polarized light-emitting device. The optically active reflective layer is configured to reflect radiation having a wavelength included in a reflection wavelength band of the optically active reflective layer. The reflection wavelength band of the optically active reflective layer is adjusted to at least partially encompass the emission wavelength band of the radiation-emitting layer.
