文摘 Mn~(3+) and Bi~(3+) co-doped Y_6WO_(12) samples with hexagonal structure were synthesized via an improved salt pyrogenation method at a temperature region of 700–1100 ℃ for 3 h. In Y_6WO_(12), Mn~(3+), substituting Y~(3+), occupies a seven-coordination site and its energy levels are treated in near Oh symmetry. The samples doped by Mn~(3+) alone emit the most intensive blue light at 420 nm under excitation at 247 nm due to charge transition (CT). The mechanism of sensitization of Bi~(3+) for Y_6WO_(12):Mn~(3+) was also analyzed by taking account of metal-to-metal chargetransfer (MMCT) from Bi~(3+) to Mn~(3+). As a consequence, the phosphor Y_6WO_(12):Mn~(3+)/Bi~(3+) can emit blue light under radiation of 370 nm, and the emission intensity is enhanced about five times by the sensitizer Bi~(3+). The optimal doping concentration of Bi~(3+) is determined as 1 at% for the emission at 420 nm in Y_6WO_(12):0.5 at% Mn~(3+) phosphors.
