N2 - A series of Ba3LaNa(PO4)3F (BLNPF): Eu2+, Pr3+ phosphors were synthesized by solid state reactions and their luminescent properties were investigated in detail. Under near-ultraviolet (n-UV) light excitation, the photoluminescence (PL) spectra of the BLNPF: Eu2+, Pr3+ phosphors consist of a broad blue emission band from Eu2+ and a group of red emission peaks as well as near infrared (NIR) emission peaks from Pr3+. These emissions not only coincide with the absorption spectra of chlorophyll and carotenoid of plants, but also overlap with the absorption of bacteriochlorophyll. Their intensities could be tuned by adjusting the energy transfer (ET) process from Eu2+ to Pr3+ to satisfy the absorption requirements for different plants and bacteria. The ET mechanism from Eu2+ to Pr3+ is demonstrated to be an exchange interaction, on the basis of the PL spectra and decay curves of the phosphors. The results suggest that BLNPF: Eu2+, Pr3+ with multicolor emission could perfectly act as phosphor candidates for application in plant growth n-UV LED.
