概要:
Sr4Al14O25:Eu2+/Dy3+ phosphor with high luminescence intensity and long afterglow duration was synthesized using 1.0 μm (α), 0.1 μm (α), and 0.05 μm (γ) particle sizes of Al2O3. SEM observation results showed that spike-like thin particles were formed when 0.05 μm γ-Al2O3 was used as raw material. Hexagonal thick particles were observed when 0.1 μm α-Al2O3 was used. But irregular, thin particles were observed while using 1 μm α-Al2O3. Photoluminescence measurements showed that both the initial intensity and the long persistency were much higher for the phosphor prepared using γ-Al2O3 of 0.05 μm particle size.
