A low-cost ZnAl2O4:Mn2+green nanophosphor for field emission display (FED) was successfully synthesized by the coprecipitation method and a two-step firing, firstly calcining at 1200 °C for 2 h in air and then annealing at 900 °C for 3 h in flowing NH3gas. The effects of the preparation process and the Mn2+concentration on optical properties of ZnAl2O4:Mn2+were investigated. The phase composition, particle morphology, photoluminescence (PL) spectra of the ZnAl2O4:Mn2+phosphor as well as low-voltage field emission properties of the FED device prepared by using the synthesized ZnAl2O4:Mn2+phosphor were examined. Similar to ZnGa2O4:Mn2+, Mn2+-doped ZnAl2O4showed two green emission bands centered at 508 and 517 nm, respectively, which originate from4T1(4G)→6A1(6S) transitions of Mn2+on Tdand Ohsites. The PL intensity reached the maximum at 0.5 at.% Mn2+. Under the low-voltage excitation, the FED device exhibited bright green emission, high voltage brightness saturation, and high color purity.
