Abstract: Hybrid inorganic light emitting device/luminescent polymer light-emitting sources for efficient and cost effective white lighting and for full-color applications and their manufacture are disclosed. The hybrid light sources include an inorganic light-emitting source such as a p-n junction diode-containing device capable of emitting a first emitted output of light and a photoluminescent polymer element positioned in the first emitted output of light, the polymer being selected to be capable of being pumped by a first portion of the first emitted output of light and when so pumped of emitting a second emitted output of light which is emitted from the device with that portion of the first emitted output remaining beyond the first portion.
