N-containing Ce₂Si_2.5Al_0.5O_3.5N_3.5 (CeSiAlON) melilite was synthesized at 1550 and 1600 °C for 5 h from CeO₂, Si, Al, and Al₂O₃ in nitrogen by using Y₂O₃ and transition-metal nitrates (Co(NO₃)₂∙6H₂O and Ni(NO₃)₂∙6H₂O) as additives. The effects of Y₂O₃ and transition-metal nitrates on the phase, microstructures and photoluminescence properties of CeSiAlON melilite were studied. The incorporation of Y₂O₃ can promote the reaction of raw materials to a low degree, and results in a unit cell shrinkage of CeSiAlON due to the smaller radius of Y atom than that of Ce atom. The transition-metal nitrates can accelerate the reaction clearly and facilitate the formation of CeSiAlON fibers. The photoluminescence (PL) properties of CeSiAlON melilite presents a board violet emission band because of the 5d-4f transitions of Ce³⁺, and the additives can enhance the PL emission intensities of specimen significantly.
