“…Phosphors convert light-emitting diodes (pc-LEDs) has been the main LED light source for plant growth lamp because of its long service life, environment-friendly and high spectral tunability. 12 More accurate light source is needed to further meet the needs of plant growth. Nitride and fluoride red-emitting phosphors have been widely researched because of their highly efficient red emission.…”

Blue and far-red light play a key role in plant growth, so it is necessary to develop blue and far-red dual emitting phosphors. However, the match between phosphors and plant pigments is not satisfactory. In this work, we synthesized a series of blue and far-red dual emission Gd 2 MgTiO 6 : Bi 3+ , Cr 3+ (GMTO: Bi 3+ , Cr 3+ ) phosphors and discussed the luminescence performance. The blue emission at 430 nm is ascribed to 3 P 1 → 1 S 0 transition of Bi 3+ and the far-red emission is ascribed to 4 T 2 → 4 A 2 and 2 E → 4 A 2 transitions of Cr 3+ . Notably, because of the energy competition between Cr 3+ ions and host materials, the luminescence tuning realized with the content of Cr 3+ doping. In addition, an energy-transfer performance occurred from Bi 3+ ions to Cr 3+ ions and the photoluminescence intensity of Cr 3+ can be enhanced by Bi 3+ . The pc-LEDs devices were synthesized by GMTO: Bi 3+ , Cr 3+ phosphor, and ultraviolet (UV) chips. Finally, the emission of GMTO: Bi 3+ , Cr 3+ phosphor matched well with the absorption spectra of plant pigments which indicated the potential applications in LED plant lamp.

“…Recently, non-rare-earth transitional-metal Mn 4+ ions, which could serve as efficient luminescent activators with a strong absorption in the range of 250–600 nm and an intense red emission covering the region from 600 to 800 nm, were widely investigated for developing new red phosphors. 3,5,19−30 Generally, Mn 4+ ions can be stable in the host matrix with an octahedral environment. 31−33 Double perovskite structure is regarded as an outstanding host material for Mn 4+ activators on account of its different crystal structures, excellent optical properties, and good chemical stability.…”

In this article, a series of novel Mn 4+ -doped Ba 2 GdTaO 6 (BGT) red-emitting phosphors were successfully synthesized via a high-temperature solid-state method. The crystal structure, morphology, and luminescent performance of the samples were investigated in detail with X-ray diffraction, field emission scanning electron microscopy, photoluminescence (PL) spectra, decay curves, and internal quantum efficiency (IQE). Excited at 358 nm, these samples showed an intense deep-red emission band peaking at 688 nm in the wavelength region of 620–800 nm. The excitation spectra of these samples monitored at 688 nm exhibited two broad excitation bands from 250 to 600 nm with peaks at 358 and 469 nm. The systematic investigation of the concentration-dependent PL properties of BGT:Mn 4+ phosphors revealed that the deep-red emission intensity reached the maximum when the Mn 4+ doping concentration was 0.6 mol %. The critical distance ( R c ) between Mn 4+ ions for concentration quenching was 36.57 Å, and the major mechanism of energy transfer among Mn 4+ activators in BGT:Mn 4+ was dipole–dipole interaction. The decay lifetimes decreased from 0.285 to 0.248 ms with the increasing Mn 4+ doping concentration from 0.2 to 1.2 mol %. The Commission Internationale de l’Éclairage coordinates of the optimal BGT:0.6%Mn 4+ sample were (0.7294, 0.2706). The values of the IQE for all BGT:Mn 4+ samples were measured, and the highest value could reach up to 62%. The above results revealed that these high-efficiency BGT:Mn 4+ deep-red-emitting phosphors had promising potential for application in indoor plant growth lighting.
