Abstract
Disclosed is a method for converting a primary electromagnetic radiation to a longer output wavelength that includes providing an energy conversion layer having a first photoluminescent material and a second photoluminescent material, exposing the energy conversion layer to the primary electromagnetic radiation, and transferring at least a portion of absorbed energy from the first photoluminescent material to the second photoluminescent material by dipolar coupling, such that the second photoluminescent material subsequently emits the longer output wavelength.
