A novel Mn4+-activated Ba3Y2WO9phosphor of double perovskite structure has been prepared via high-temperature solid-state reaction method. The phosphor can emit red emission located at ~692 nm, which greatly overlaps with the absorption spectra of chlorophyll and phytochrome in the red light range. the intensest excitation band of the phosphor originating in the O2−→Mn4+charge transfer and the4A2g→4T1gof Mn4+centres at ~367 nm, while the sub intense excitation band formed by4A2g→4T2gtransition is located in the yellow-green light region (~535 nm). The excitation and emission performance of the phosphor indicates its potential application in light-conversion film/glass for greenhouse cultivation since it can convert not only UV but also yellow-green light into red emission. The optimal doping concentration of Mn4+in the Ba3Y2WO9host is 0.3 mol%, beyond which energy transfer between Mn4+ions based on d-d interaction results in fluorescence quenching. Besides, the crystal field strength and thermal stability of the sample are also discussed.
