摘要：
Ba2Mg2Al6Si9O30 (BMAS):Ce3+, Tb3+ phosphor powder was synthesized by a high-temperature solid-state method. The excitation spectra of BMAS:Ce3+, Tb3+ phosphors showed a strong and broad absorption band, which ranged from 220 nm to 380 nm. With the excitation of 350 nm, the characteristic emission peaks centered at 544 nm of Tb3+ and at 420 nm of Ce3+ were observed. With increased Ce3+ concentration from 0.01 to 0.13, energy-transfer efficiency increased from 3.26% to 76.59%. Adjustment of the Ce3+ to Tb3+ ratio can induce the emission peak of the samples to change from blue to green.
