Flux induced highly efficient and stable phosphor Sr₂ScSbO₆:Mn⁴⁺ for plant growth lighting

Abstract

Anti-seasonal vegetables and greenhouse planting patterns are being rapidly promoted, and the domestic market demand for agricultural lighting has increased significantly. Far-red light required for plant growth urgently requires development....

An Al3+-incorporated Ca2LuNbO6:Mn4+ oxide phosphor with dramatic deep-red and far-red emission bands

“…Blue, red, and far-red light contribute to plant growth through different mechanisms, such as phototropism, photosynthesis, and photomorphogenesis. 54 In order to evaluate the performance of Mn 4+ doped CLN phosphors in practical applications, the emission spectrum of the CLN 0.6 A 0.4 :0.3%Mn 4+ phosphor was compared with the absorption spectra of plant phytochromes Pr and Pfr (Fig. 14(b)).…”

Near‐unity quantum efficiency wavelength‐tunable NIR phosphors (Sr2−yCay)Sc1−xSbO6: xFe3+ with excellent thermal stability

“…One can see that it is characteristic of the monoclinic crystal system with the P 2 1 / c space group. Both Sc 3+ and Sb 5+ are coordinated with six O atoms, affording ScO 6 and SbO 6 octahedra 14 . Figure 1B illustrates the XRD patterns of Fe 3+ ‐doped SS 1− x S: x Fe 3+ ( x = 0%−3%) samples.…”

Ca18Na3Y(PO4)14:Eu2+,Mn2+: a novel single-phase dual-emission phosphor and its spectral modulation by Mg2+ for plant lighting and WLEDs

“…12 The Eu 2+ -doped SrAl 2-Si 2 O 8 phosphor can emit blue-cyan light covering 400-500 nm, which is more suitable for plant growth. 13 For red phosphors used in plant lighting, Cr 3+ -or Mn 4+ -activated phosphors with far-red and near-infrared emitting light have been commonly reported, such as LaSrZnNbO 6 :Mn 4+ , 14 Sr 2 ScSbO 6 :Mn 4+ , 15 LiMgAlF 6 :Cr 3+ , 16 Mg 2 SnO 4 :Cr 3+ , 17 and so on. Their emission peaks are located at around 700 nm or even longer wavelength regions, corresponding to the absorption ranges of the P FR .…”
