摘要：

A novel deep-red-emitting phosphor Ca2ScNbO6:Mn4+ is prepared via a high-temperature solid-state reaction and its luminescent properties are systematically investigated. The results show that Mn4+-activated Ca2ScNbO6 phosphors have broad absorption in ultraviolet region, and show bright deep-red emission at 692 nm. The optimal doping concentration, crystal-field strength, internal quantum efficiency, and mechanism of concentration and thermal quenching effects are discussed in detail. Moreover, NaF flux is screened out to improve both luminescent intensity and morphology of the phosphor. Finally, a red light-emitting diode (LED) lamp is fabricated with as-prepared Ca2ScNbO6:Mn4+ phosphors and a 365 nm LED chip. The electroluminescence spectra show a good overlapping with phytochrome P-R and P-FR absorbance. The results provided the as-synthesized Ca2ScNbO6:Mn4+ phosphors a great potential in plant growth lighting.
