Phosphors
V 1250

Preparation of Small-Sized Particles of Eu2+-Activated Barium Magnesium
Aluminate Phosphors. — (Ba1-x Eu.x)MgAl10O17 and (Ba1-x Eux)Mg2Al 16O27
(0.01 ≤ x ≤ 0.08) phosphors are synthesized by decomposing aqueous solutions of the
metal nitrates with diformyl hydrazine at about 500 °C followed by firing at 1300 °C
for 1 h under a reducing atmosphere. The novel synthesis method yields phosphors with
better brightness and higher luminescence intensity than phosphors prepared by conventional methods. — (HAN*, S.-D.; HAN, C.-H.; Indian J. Chem., Sect. A: Inorg.,
