Ca(1-x)Eu(x)AlSiN3 is currently one of the best known red-emitting materials for LED applications. We will present the experimental results of structural and optical properties of Ca(1-x)Eu(x)AlSiN3 samples. Ca(1-x)Eu(x)AlSiN3(x=0.02, 0.04, 0.06, 0.08, 0.1) samples were successfully synthesized by the high-temperature solid state reaction method. The structure and luminescence properties of samples were investigated by x-ray diffraction and spectroscopic measurements. The Ca0.96Eu0.04AlSiN3 sample shows the strongest red fluorescence emission peak at 670nm under the excitation wavelength of 450nm.
