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.抄録:Sr4Al14O25:Eu2+/Dy3+ phosphor with high luminescence intensity and long afterglow duration was synthesized using 1.0 μm (α),
