Abstract

Ce3+ and Tb3+co-doped calcium aluminates luminescent material (Ca3Al2(OH)12: Ce3+, Tb3+) was synthesized at 453 K in hydrothermal system without any protective atmospheres. All the reactants used in the system were simple inorganic salts. The crystallinity and luminescent property of as-synthesized compound were investigated using X-ray diffraction and luminescence spectrometer. The compound formula was confirmed to be Ca3Al2(OH)12. The emission spectrum showed that only typical Tb3+ emission was observed and the emission from Ce3+ was almost not observed, which should be attributed to the energy transfer from Ce3+ to Tb3+ in the compound. The emission peaks at about 486 nm, 498 nm, 540 nm, 549 nm, 582 nm, 595 nm and 623 nm should be assigned to 5D4-7F6, 5D4-7F5, 5D4-7F4, and 5D4-7F3 transitions of Tb3+ ions. The weak emission peak at about 380 nm should be assigned to the emission of Ce3+ ions in the compound.
