Preparation and optical properties of a novel double-perovskite phosphor, Ba 2 GdNbO 6 :Mn 4+ , for light-emitting diodes

Preparation, characterization, and luminescence properties of double perovskite SrLaMgSbO6:Mn4+ far-red emitting phosphors for indoor plant growth lighting

“…4(d) shows the luminescence decay curves of the SLMS:xMn 4+ (x ¼ 0.05%, 0.6%, 0.8%, 1.0%, and 1.2%) phosphors. The decay lifetimes of the as-prepared samples were obtained by using the following double exponential expression: [50][51][52][53]…”

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.…”

Novel Mn4+ doped Ca2GdSbO6 red–emitting phosphor: A potential color converter for light‐emitting diodes

“…Currently, double–perovskite compounds, including Gd 2 ZnTiO 6 , CaLaMgWO 6 , Ba 2 GdNbO 6 and so on, have been extensively investigated as the matrixes of luminescent materials owing to their chemical and thermal stability . Among them, the compound with A 2 BB'O 6 structure has attracted much concern; it possesses abundant [B/B'O 6 ] octahedrons to provide enough suitable sites for Mn 4+ ions incorporating in and giving rise to red emission .…”
