Crystal Structure and Luminescence of SrAl₂O₄: Eu²⁺,Dy³⁺ Phosphor Prepared by Nano-Pseudoboehmite Particulate Peptizing Method

Abstract:

Eu²⁺, Dy³⁺ co-doped strontium aluminate (SrAl₂O₄) phosphor with high brightness and long afterglow were prepared by nano pseudo-boehmite particulate sol method. The precursor was prepared by peptizing AlOOH powders with HNO3 as peptize agent. The influence of preparation parameters on crystal structure and luminescent properties of the phosphor have been studied systematically. Monoclinic SrAl₂O₄ host with single-phase can be obtained by controlling sintering temperature at 1200°C, 4Wt%B2O3 and RSr/Al=0.34. The sample exhibits an intensive emission peak at 515 nm and the luminescent intensity decay with I=277.78t-1.079 .
