Full Red-Band Emitting of Bamgp2o7: Xmn2+ Phosphor for Plant-Growth Illumination

Abstract

Red light can promote plant photosynthesis and accelerate plant growth. It is very important to find an efficient red phosphor for the development of modern agriculture. In this work, a series of Mn2+-activated BaMgP2O7 phosphors were fabricated by a high-temperature solid-phase method. The phase structure, micromorphology and luminescent properties were investigated in detail. Under the excitation of 410 nm light, it was found that the luminescent spectra of BaMgP2O7: xMn2+ phosphors cover the full wavelength band of red light in the visible light region. The emission intensity at the temperature of 483 K remains 72.67% of the emission intensity at the reference temperature (T=303 K), indicating that the good thermal stability of phosphors. There was a large overlap between the emission spectra of obtained phosphors and the absorption spectra of PR and PFR, indicating that the great application potential of BaMgP2O7: xMn2+ phosphors for plant growth lighting.
