| Abstract |
To improve luminescent properties of the phosphor, spherical BaMgAl10O17:Eu2+ particles
have been synthesized using a liquid phase reaction composed of two-stage precipitations. This
phosphor particles exhibited uniform size (0.4 ㎛) with narrow distribution and were well-dispersed
without agglomeration. The single phase of phosphor was formed by firing at the temperature of
about 1350°C. The preparation conditions in this synthetic process for spherical BaMgAl10O17:Eu2+
particles were optimized on the basis of emission intensity by the excitation at 147 nm. The emission
spectra showed the typical broad band due to the transition of Eu2+ activator from 4f65d1 to 4f7 in
BaMgAl10O17:Eu2+. The maximum emission intensity for this spherical blue phosphor was obtained
by reduction treatment at 1450°C. |
