Abstract
CaYAlO4:Eu3+ phosphors have been synthesized by a solid state method, and characterized by X-ray powder diffraction and photoluminescence (PL). Under the excitation of 147 nm, the synthesized phosphors indicated PL characteristics of the Eu3+ center with the main emission peak at a wavelength of 611.5 nm. The emission intensity depended on synthesis temperature and Eu3+ doping concentration. The highest PL intensity was found for the Ca0.97Eu0.03YAlO4 synthesized at 1400°C for 2 h.
