Abstract

Light-emitting photoluminescent (PL) cell configured to abate thermal quenching when exposed to high levels of radiant excitation; methods and systems of using the same for horticultural growth lighting and other lighting applications. Embodiment of a method for fabricating such cell includes vapor-depositing a first layer of optically-transmissive and thermally-transmissive (> 30 W/m-K; preferably > 10030 W/m-K; more preferably > 500 W/m-K) auxiliary material on an appropriately-shaped heatsink substrate. A PL material (preferably, a composite of chosen phosphor with the auxiliary material) is then applied on top of the first layer, followed by vapor-depositing a second layer of auxiliary material to encapsulate/seal the PL material between first and second layer
