Abstract A red-emitting CaZrO3:Eu3+ phosphor has been prepared by solid state reaction and its luminescent properties are studied. The crystal structure is investigated by the x−ray diffraction. Through energy transitions of 5D0→7FJ (J=0, 1, 2, 3) in Eu3+ ions, the emission spectrum of the phosphor shows a series of narrow bands under near−ultraviolet light and the strongest peak locates at 613 nm. The emission intensity of Ca1-xZrO3:xEu3+ phosphor will reach the maximum as the molar concentration of Eu3+ is 5 mol%.
