文摘

Sr3Al2O6:Eu2+, Dy3+ phosphors were synthesized by the polymer precursor method. The X-ray powder diffraction patterns show that the samples have a cubic structure with a space group of Pa3. In the excitation spectrum, the phosphors show a wide absorption in the UV region from 250 to 450?nm, which corresponds to the crystal field splitting of the Eu2+ d-orbital. All the emission spectrum of Sr3Al2O6:Eu2+, Dy3+ phosphors show the broad band emission peaked at about 518?nm, which can be ascribed to the typical 4f65d1?→?f7 transitions of Eu2+ ions. And the best dopant concentration of Dy3+ ions for Sr3Al2O6:2?mol%Eu2+, xDy3+ phosphors is 2?mol%. The excitation wavelengths have no influences on emission peaks, but have clear influences on emission intensities.
