摘要：

Alkaline earth monoaluminate phosphors activated with Eu2+ were synthesized by microwave processing and alkaline earth hexaaluminate phosphors activated by Eu2+ were synthesized by hydrothermal reactions. The emission spectra of the monoaluminates are similar to phosphors prepared by high-temperature firing except for BaAl2O4 which emits farther in the blue. The spectra of the hexaaluminate phosphors in general have their emission peak at different wavelengths than what are nominally the same compositions prepared by high-temperature firing.
