Low-temperature synthesis of fine BaMgAl10O17:Eu2+ phosphor based on the solubility isotherms

Emission spectra under the VUV (left) and UV excitation for the samples prepared at 1000 °C (a), 1150 °C (b), 1250 °C (c), and 1350 °C (d) with commercial BAM (dotted line). UV excitation well reflects the luminescent properties of the bulk particle, while under VUV excitation the surface character would have a great influence on the luminescent properties, especially for the fine phosphor particle.
