Double perovskite LiLaMgWO6:Eu3+ novel red-emitting phosphors for solid sate lighting: Synthesis, structure and photoluminescent properties

Synthesis and photoluminescence characteristics of high color purity Ba3Y4O9:Eu3+red-emitting phosphors with excellent thermal stability for warm W-LED application

“…The PLE spectrum contained a broad band 7 F 0 / 5 D 3 , and 7 F 0 / 5 D 2 transitions, respectively. [35][36][37] Particularly, the excitation intensities of 7 F 0 / 5 L 6 (396 nm) and 7 F 0 / 5 D 2 (469 nm) transitions were almost equivalent. Because the energy of near-UV light was larger than that of blue light, under the same situation, the PL intensity of BYO:0.25Eu 3+ phosphors upon 396 nm excitation was stronger than that upon 469 nm, as shown in the PL spectra.…”

Mn4+-activated BaLaMgSbO6 double-perovskite phosphor: a novel high-efficiency far-red-emitting luminescent material for indoor plant growth lighting

“…34,35 The perovskite-type compounds are potential hosts for luminescent materials due to their excellent optical properties and diversity of their structure and composition. [36][37][38][39][40][41][42][43][44] Therefore, double perovskite BaLaMgSbO 6 (BLMS), which contains many [SbO 6 ] octahedrons, would be a novel good host for doping Mn 4+ ions.…”

Luminescence properties and energy transfer of K3LuF6:Tb3+,Eu3+ multicolor phosphors with a cryolite structure

“…[15][16][17][18][19][20] Due to 5 D 0 / 7 F 2 electronic transitions, Eu 3+ -doped luminescent materials can emit strong red light. 21 Tb 3+ has been widely used together with Eu 3+ to produce multicolor emission by means of energy transfer, such as in CaMoO 4 :Tb 3+ /Eu 3+ , 22 Ba 2 La 3 (SiO 4 ) 3 -F:Tb 3+ /Eu 3+ , and 23 Na 2 MgSiO 4 :Tb 3+ /Eu 3+ . 24 However, until now, there have been no reports on the crystal structure, luminescence properties and energy transfer investigations of multicolor-emitting K 3 LuF 6 :Tb 3+ ,Eu 3+ phosphors with a cryolite structure.…”
