We described the synthesis and luminescence of Ca 1.5 Y 1.5 Al 3.5 Si 1.5 O 12 :Ce 3+ phosphor for light emitting diode (LED). The crystallinity, morphology, structure, and luminescence spectra were examined by X-ray diffraction, field emission-scanning electron microscopy and photoluminescence spectroscopy. The results showed that Ca 1.5 Y 1.5 Al 3.5 Si 1.5 O 12 :Ce 3+ phase was a dominating phase with little impurity phase peaks of Y 2 O 3 when the sintered temperature reached to 1400°C. Field emission scanning electron microscopy (FE-SEM) images showed the particle size of the phosphor was about 3 μm. Meanwhile, the excitation and emission spectra indicated that the as-prepared phosphors could be effectively excited by blue (460 nm) light and the excitation spectrum showed a broad band extending from 400–500 nm, while emission spectrum showed a broad yellow band peaking at 534 nm. The decay curve at the emission peak consisted of fast and slow components. The Ca 1.5 Y 1.5 Al 3.5 Si 1.5 O 12 :Ce 3+ should be a promising yellow phosphor for near blue-based white-light-emitting diodes (LEDs).
