Luminescence and Energy Transfer of Color-Tunable BaMg2Al6Si9O30: Ce3+, Tb3+ Phosphor

Ba 2 Mg 2 Al 6 Si 9 O 30 (BMAS):Ce 3+ , Tb3 + phosphor powder was synthesized by a high-temperature solid-state method. The excitation spectra of BMAS:Ce 3+ , Tb 3+ phosphors showed a strong and broad absorption band, which ranged from 220 nm to 380 nm. With the excitation of 350 nm, the characteris...

Description
Summary:Ba 2 Mg 2 Al 6 Si 9 O 30 (BMAS):Ce 3+ , Tb3 + phosphor powder was synthesized by a high-temperature solid-state method. The excitation spectra of BMAS:Ce 3+ , Tb 3+ 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 Tb 3+ and at 420 nm of Ce 3+ were observed. With increased Ce 3+ concentration from 0.01 to 0.13, energy-transfer efficiency increased from 3.26% to 76.59%. Adjustment of the Ce 3+ to Tb 3+ ratio can induce the emission peak of the samples to change from blue to green.
