Abstract

The relation between properties of strontium aluminate phosphor and Al/Sr ratio was investigated. A series of strontium aluminate phosphors with different Al/Sr ratios from 1.0 to 12.0 were synthesized by solid-state method. The samples were characterized by X-ray diffraction and photoluminescence spectra. The results reveal that single phases of SrAl₂O₄:Eu²⁺, Dy³⁺, Sr₄Al₁₄O₂₅:Eu²⁺, Dy³⁺ and SrAl₁₂O₁₉:Eu²⁺, Dy³⁺ are obtained with Al/Sr ratios of 2.0, 3.5 and 10.0 respectively. When Al/Sr selects other values, the final products are mixture. Moreover, the emission spectra of the samples shift to blue-ultraviolet short wavelength from yellow-green long wave with the increase of Al/Sr ratios, which result from change of products' composition.
