中文摘要	by using inorganic salts as raw materials and citric acid as complexing agent, spinel oxide znga2o4 and mn2+, eu3+-doped znga2o4 phosphor powders were prepared by a citrate-gel process. x-ray diffraction (xrd), tg-dta, ft-ir. and luminescence excitation and emission spectra were used to characterize the resulting products. the results of xrd reveal that the powders begin to crystallize at 500 degreesc and pure znga2o4 phase is obtained at 700 degreesc, which agrees well with the results of tg-dta and ft-ir. in the crystalline znga2o4, the eu shows its characteristic red (615 nm, d-5(0)-f-7(2)) emission with a quenching concentration of 5 mol% (of ga3+), and the mn shows green emission (505 nm, t, a,) with a quenching concentration of 0.1 mol% (of zn2+). the luminescence mechanism of znga2o4:mn2+/eu3+ is presented.
