Fabrication and characterization of a phosphor based photon conversion film

Enhancement of efficiency and CCT uniformity for red phosphor thin films, red LEDs and laminated white LEDs based on near-ultraviolet LEDs using MgO nanoparticles

“…In response to this phenomenon, researchers used stratication or partition of PTFs to attenuate the re-absorption and improve the device performances. [8][9][10][11] As phosphor conversion materials, [12][13][14] PTFs can convert the absorbed photons into an emission spectrum with specic energy distribution. With wide application range, in the display eld, 15,16 PTFs can effectively improve color uniformity and light extraction efficiency of uorescent screens; in the eld of photovoltaics, 17,18 they can effectively improve utilization efficiency of solar energy; in the eld of solid-state lighting, 19,20 also known as remote phosphors, they have the advantages of improving uniformity and photo-thermal stability.…”
