Abstract
Disclosed herein are phosphor compositions comprising a BAM phosphor BaMgAlO:Euand at least one other hexaaluminate that may also be europium activated. The BAM may be mixed with any number of different kinds of heaxaaluminates having a similar crystal structure. The aluminum ratio may also be adjusted to alter the defect structure or to produce a second phase. Addition of another hexaaluminate to BAM enhances emission intensity and resistance to degradation, which is beneficial to applications such as plasma display panels.
