Eu3+-based efficient red phosphors Y1-Eu Ga3(BO3)4 (0 < x ≤ 1): A potential candidate for near ultraviolet LEDs with high thermal stability

Novel rare earth free phosphors CsMg2P3O10: Mn2+ with efficient and ultra‐broadband red emission for plant growth LEDs

“…Red and far‐red emissions can be effectively absorbed by photosynthesis pigments P R and P FR , which play a dominant role in promoting plant growth and biomass accumulation. 6,7 Nowadays, rare earth ions (such as Eu 2+ and Eu 3+ ) doped phosphors are crucial components to generated red and far‐red emissions for plant‐growth LEDs 8–10 . Among them, the Eu 2+ ‐doped nitrides such as (Sr, Ca)AlSiN 3 : Eu 2+ 11 and (Sr 1‐ x Ca x ) 2 Si 5 N 8 : Eu 2+ 12 show the highest intensity and narrow full width at half‐maximum (FWHM).…”

However, the synthesis process requires harsh synthetic conditions of high temperature (> 1800 • C) and pressure in a reductive atmosphere.…”
