Down-Conversion Nitride Materials for Solid State Lighting: Recent Advances and Perspectives

Abstract: Advances in solid state white lighting technologies witness the explosive development of phosphor materials (down-conversion luminescent materials). A large amount of evidence has demonstrated the revolutionary role of the emerging nitride phosphors in producing superior white light-emitting diodes for lighting and display applications. The structural and compositional versatility together with the unique local coordination environments enable nitride materials to have compelling luminescent properties such as… Show more

“…Over the last couple of years, the hunt for new alternative light sources to replace incandescent light bulbs has resulted in the creation of countless phosphors for the use in phosphor converted light‐emitting diodes (pc‐LEDs) 1, 2, 3, 4. In these pc‐LEDs, a short wavelength emitting light source (UV to blue LED) is combined with additional converting phosphors, which emit light of longer wavelengths, to compose the desired color 5, 6, 7, 8.…”

“…In addition, another important characteristic of Eu 2+ ‐activated phosphor is the relatively small Stoke shifts and short decay time . Recently, great efforts have been devoted to develop an efficient blue‐ and green‐emitting phosphors, but only some nitrides/oxynitrides phosphors demonstrate suitable luminous efficiency and thermal stability . Furthermore, these nitrides/oxynitrides phosphors require a critical synthetic condition, such as high reaction temperature, high pressure nitrogen, expensive raw materials, which restrict the application of it for WLEDs widely …”

“…There is a trade‐off between luminous efficacy and high CRI in all types of white LEDs, which means that the improvement in one usually brings about the reduction of the other. The emission peak should be at ~630 nm with relatively narrow band for the optimum balance …”
