We reported two kinds of photoluminescence materials of red phosphor BaMg

that we synthesized for the first time. With the aid of orthogonalizing method of the experiment design

the optimum proportion of host materials and synthesis temperature are determined. The mole ratio of SiO

/BaCO

/MgO is 2.14:1:1.96 at 1230℃. The emission and excitation spectra of the two kinds of luminophors are studied.We have investigated some factors that affect emission intensity of the materials. It is found either of Pb

and Ag+ have sensitive effect on Eu

in BaMg

emission intensity sensitized by Pb

and Ag+ is increased 230% and 80% respectively. With the doping of a little V2O5 into BaMg

the emission intensity ef Eu

is increased 160%. In either of these two materials

the emission intensity is increased 5-15% by the charge compensation of the alkaline metal ions (Li

).It is found that the brightness of BaMg

simple technique and the good application characteristics.
