title = "Green light-excitable Ce-doped nitridomagnesoaluminate Sr[Mg2Al2N4] phosphor for white light-emitting diodes",
abstract = "A yellow-emitting Ce-doped Sr[Mg2Al2N4] phosphor was synthesized using all-nitride starting materials via gas pressure sintering (GPS). The phosphor is effectively excitable by green light (510 nm). Homogeneous and inhomogeneous broadening is responsible for appearance of broad luminescence that cover the spectral region from 500 to 700 nm with maximum emissions at 580 and 620 nm. Pressure-dependent luminescence results show the significant red shift of the luminescence and excitation bands and reveal the presence of additional pathway for nonradiative deactivation. The Sr0.985[Mg2Al2N4]:Ce0.0153+ phosphor retained ~65% of its intensity at 150°C. With a blue LED excitable pc-LED package, where it is coated on top of the β-SiAlON:Eu2+-coated blue LED chip and white light with CCT = 4595 K and Ra = 61 with 20 lm/W efficacy was generated. This Ce3+-doped phosphor demonstrates how it can substitute for the emission of two phosphors.",
