Summary: A single-phase full-spectrum emission Ca9NaLu0.667(PO4)(7) (CNLP):Eu2+/Mn(2+) phosphor was synthesized and its luminous color was adjusted by changing the content of Mn(2+). The average bond length obtained using Rietveld refinements was used to analyze the occupancy of Eu2+/Mn(2+). The energy transfer process of Eu2+ ? Mn(2+) was discussed, and the ET efficiency reached 77.81%.

Summary: A high temperature solid state method was used to prepare Na3Gd(PO4)(2):Eu2+,Mn2+ phosphors with good thermal stability. The phosphor exhibits a wide excitation range and shows blue, white, and red light emission under different Mn2+ doping levels. The prepared phosphors also demonstrate good thermal stability and can be considered as potential candidates for UV/NUV light-excited w-LED applications.

Summary: A new dual-emitting phosphor Na2BaMg(PO4)2: Eu2+, Mn2+ is prepared via conventional sintering method. The phosphor exhibits efficient double-band emissions at 415 and 620 nm, which match well with the absorption spectra of chlorophyll A/B and phytochrome in plants. It shows good thermal stability (75% emission intensity maintenance at 200 degrees C) and high quantum efficiency (QE > 80%). A prototype LED fabricated using this phosphor and NUV chip demonstrates two distinct emission peaks modulating an optimum action spectrum for plant absorption. Na2BaMg(PO4)2: Eu2+, Mn2+ shows great potential as a converted component for plant growth LEDs.
