“…5. It is found that the excitation spectrum can be fallen into two parts according to the band-gap energy level of YAG at 180 nm [15]. The excitation bands between 180 and 300 nm, which locate at 197, 226 and 272 nm, respectively, are attributed to the 4f 8 -4f 7 5d 1 transitions of Tb 3+ [16].…”

Materials containing rare earth ions with photoluminescent properties have been investigated as efficient phosphors for applications in photonics. In this work We reports on preparation of Eu 3 þ -doped Al 2 O 3 with different concentrations of Eu 3 þ , in relation to the amount of moles of Al 3 þ , has been prepared using a simple and inexpensive synthesis. XRD showed that the alumina-based materials calcined at 400 and 600 1C were predominated by the γ-Al 2 O 3 phase. However the materials heat-treated above 800 1C showed mixture of γ and α-Al 2 O 3 phases. SEM presented results demonstrating that the heat-treatment at increased temperature favors a larger particle size with inhomogeneous morphology. It was observed with photoluminescence spectroscopy that theEu 3 þ -doped Al 2 O 3 materials showed intense photoluminescence emission around 612 nm under excitation at 394 nm. This emission in the visible region was assigned to a down-shifting phenomenon attributed to the intraconfigurational f-f transitions of Eu 3 þ . Intense emission around 693 nm assigned to Cr 3 þ were observed, and the intensity is controlled by the heat-treatment temperature of synthesis. The lifetime found for these materials are of the order of milliseconds at 612 nm. In summary the materials obtained in this work show properties than can be used for photonics applications.
