Abstract

Series of CaAl4O7:Eu3+ were firstly synthesized as high-purity luminescence ceramic powders by using Self-Propagating Combustion Synthesis (SPCS) methods. XRD showed the unit cell of CaAl4O7:Eu3+ was confirmed monoclinic system and belonged to C2/c space groups. Lattice constant refinement was a=1.2888nm, b=0.8887nm, c=0.5445nm, β=106.9264°, Z=1. Luminescence spectra analysis indicated all peaks were attributed to 5D0→7FJ (J = 0, 1, 2, 3, 4) transition at 578nm, 590nm, 616nm, 649nm and 701nm, respectively, and energy transfer coming from host to Eu3+ enhanced luminescence intensity. FT-IR spectra investigated vibration feature of the samples. SEM revealed the samples had smooth surface, the better crystallization and ~ 1 μm size.
