A series of Cs2NaBiCl6:Mn2+ double perovskite phosphors were prepared via liquid-phase synthesis, and their structures and luminescent properties were investigated by X-ray diffraction and fluorescence spectroscopy. The result show that with the gradual introduction of Mn2+, localized excitations centered on Bi3+ ions in the host lattice Cs2NaBiCl6 strongly absorb near-UV light, and the energy transfer between Bi3+ and Mn2+ promotes the electron transition between atomic d orbitals, thus leading to an intense orange-yellow photoluminescence. The photoluminescence reduces when the manganese-bismuth molar ratio is 0.7 due to the concentration quenching effect. Also, a broad emission peak centered at 590 nm is assigned to the 4T1→6A1 transition of octahedrally coordinated Mn2+. Based on the excitation spectrum, there are some peaks at 354 nm that arise from 6s2→6s16p1 excitations of Bi3+ions. It is indicated that Cs2NaBiCl6:Mn2+ could be a promising fluorescent phosphor synthesized without the use of expensive reagents and toxic elements materials.
