Abstract
Uniform Al2O3 : Tb3+ samples were successfully fabricated via a hydrothermal method and subsequent thermal decomposition of Tb3+ doped precursors. Scanning electron microscopy results showed Tb3+-doped Al2O3 was stalk-like with an average length about 1.5 μm. Photoluminescence spectra indicated that the 5D4 → 7F5 (545 nm) electric dipole transition was most intense upon excitation at 227 nm. It is shown that 1.5 mol.% doping concentration of Tb3+ ions in Al2O3 : Tb3+ is optimum. According to Dexter's theory, the critical distance between Tb3+ ions in Al2O3 for energy transfer was determined to be 14 Å.
