Journal ArticleDOI
Synthesis and optical properties of Li3Ba2La3(MoO4)8:Eu3+ powders and ceramics for pcLEDs
Arturas Katelnikovas,Arturas Katelnikovas,Julian Plewa,Simas Sakirzanovas,Danuta Dutczak,David Enseling,Florian Baur,Holger Winkler,Aivaras Kareiva,Thomas Jüstel +9 more
TL;DR: In this paper, a series of polycrystalline Li3Ba2La3−xEux(MoO4)8 samples were prepared by the conventional solid-state reaction and the phase formation of the samples was investigated by X-ray diffraction measurements.
Journal ArticleDOI
Synthesis and optical properties of yellow emitting garnet phosphors for pcLEDs
A. Katelnikovas,Simas Sakirzanovas,Danuta Dutczak,Julian Plewa,David Enseling,Holger Winkler,Aivaras Kareiva,Thomas Jüstel +7 more
TL;DR: In this paper, a series of CaY 2 Al 4 SiO 12 :Ce 3+ garnet-type luminescent materials was prepared by a sol-gel combustion technique, and all samples were characterized by powder X-ray diffraction (XRD), thermal quenching (TQ), fluorescence lifetime, and photoluminescence (PL) measurements.
Journal ArticleDOI
The effect of Al–O substitution for Si–N on the luminescence properties of YAG:Ce phosphor
Małgorzata Sopicka-Lizer,D. Michalik,Julian Plewa,Thomas Juestel,Holger Winkler,Tomasz Pawlik +5 more
TL;DR: In this paper, the effect of various Si-N substitution degree on the crystal structure and optical properties of yellow YAG:Ce phosphor commonly used with combination of InGaN in white LEDs was described.
Journal ArticleDOI
The influence of Ag on univariant reactions and the oxygen content of the eutectic melt in the Y–Ba–Cu–(Ag)–O system
TL;DR: In this paper, the influence of Ag admixtures on the phase equilibria of YBa2Cu3O7−δ near the liquidus surface was investigated at 0.21×105 Pa oxygen partial pressure using thermoanalytic methods.
Journal ArticleDOI
Synthesis and optical properties of green emitting garnet phosphors for phosphor-converted light emitting diodes
Arturas Katelnikovas,Julian Plewa,Danuta Dutczak,S. Möller,David Enseling,Holger Winkler,Aivaras Kareiva,Thomas Jüstel +7 more
TL;DR: In this paper, a series of Ce 3+ doped CaLu 2 Al 4 SiO 12 garnet phosphors were prepared by a sol-gel combustion technique, and all samples were characterized by powder X-ray diffraction (XRD), thermal quenching (TQ), fluorescence lifetime and photoluminescence (PL) measurements.
