“…The PL emission spectrum of the Sm 3+ -activated Figures 7 and 8 (RHS), respectively, which were monitored under excitation at 406 nm. All the emission spectra exhibited a sharp red orange emission at 646 nm, and consisted of several sharp peaks at 563, 599, 646, and 705 nm, which are assigned to the 4 G 5/2 → 6 H 5/2 , 4 G 5/2 → 6 H 7/2 , 4 G 5/2 → 6 H 9/2 , and 4 G 5/2 → 6 H 11/2 transitions, respectively [23]. Among these, the 646-nm ( 4 G 5/2 → 6 H 9/2 ) peak showed the maximum intensity.…”

Deep red phosphor-based LEDs play a crucial role in plant growth applications, where the LED emission covers the phytochrome (Pr) absorption. In this context, a series of Sm 3+-activated Li 3 BaSrLn 3 (MO 4) 8 :Sm 3+ [Ln = La Gd and Y; M = Mo and W] deep red phosphors were synthesized using the solid-state method. The outcome of the PXRD patterns suggests that the synthesized phosphors were crystallized in a monoclinic structure with the space group C2/c. SEM analysis was executed to study the morphology of the phosphors, and an FT-IR study was performed to study the stretching frequency of the MO/W-O bond in the (Mo/W)O 4 groups. All the Sm 3+-activated phosphors showed intense emission at 646 nm due to their 4 G 5/2 → 6 H 9/2 transition and exhibited excellent thermal stability (> 72% at 423K). The selected phosphors showed internal quantum efficiency at around 30%. The pc-LEDs were fabricated with the combination of near-UV LED and the synthesized deep-red phosphors. Besides, the emission spectrum of the fabricated LED was compared with the phytochrome Pr absorption spectrum for de plant growth application. These results suggest that the synthesized phosphor can be useful in the white LED fabrication to improve the CRI and can also be beneficial in the plant growth field.

The red phosphor Y2Mo4O15:Eu3+ calcined at different temperatures is obtained by a solid‐state method, and is investigated in this article. Usage of solid‐state method with the combination of five different calcination temperatures (500, 550, 600, 650, and 700 °C) leads to the formation of pure monoclinic phase in all samples apart from the one calcined at the lowest temperature. Crystallite size obtained by Rietveld refinement is in the range of 38–55 nm. Scanning electron microscopy analysis confirms the presence of agglomerates. Luminescence emission spectra and emission decay curves are measured for all pure samples, and parameters derived from these measurements are used for Judd–Ofelt analysis. International commission on illumination (CIE) chromaticity diagram confirms the presence of pure red emission and high quantum efficiency.
