PhosphorsV 1250 Effect of H3BO3 on Structure and Photoluminescence of BaAl12O19:Mn2+ Phosphor

under VUV Excitation. — The green phosphor BaAl11.9O19:0.1Mn2+ is prepared by solid state reaction of BaCO3, Al2O3, MnCO3, and 7.0 wt.% H3BO3 as a flux (5% H2/N2, 1300 °C, 4 h). The samples thus prepared show significantly enhanced photolumi-nescence intensity. — (ZHOU, J.; WANG*, Y.; LIU, B.; LU, Y.; J. Alloys Compd. 484 (2009) 1-2, 439-443; Dep. Mater.
