Abstract

Ce³⁺ -doped strontium alumino-silicates (Sr₁₋ᵥMᵥ)₁₊ᵧ Al₂₋ₓBₓSiᵧO₄₊₃ᵧ (M:Ca,Mg,Ba) were prepared using solid-state reactions at 1200⁰C for 2 h in a weakly reductive atmosphere of 5% H₂-95% N₂. The X-ray diffraction measurements revealed that the products have a good crystallization, and the resultant phosphors show broad emissions centered at 400 nm, with a long-persistence of several minutes (k=0.02–0.10 sˉ¹). These luminescent properties are considered good enough for novel applications in photo catalysis, which will be the objective of further developments.
