Title: Synthesis and control the morphology of Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+}/Eu{sup 2+},Mn{sup 2+} phosphors by precipitation method

Abstract

Highlights: • Use facile and mild precipitation method obtained Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+}/Eu{sup 2+},Mn{sup 2+} phosphors. • Through controlling the morphology to tune the photoluminescence properties. • The columnar structure Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+} phosphor shows better emission intensity. • Self-assembled phenomenon appears by changing the Mn{sup 2+} concentration of the Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+},Mn{sup 2+} phosphor. - Abstract: Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+}/Eu{sup 2+},Mn{sup 2+} phosphors have been synthesized by the facile and mild precipitation method and they are characterized by X-ray powder diffraction, scanning electron microscopy, photoluminescence spectra. The SEM results indicate the obtained Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+} phosphors have the columnar structure and the Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+},Mn{sup 2+} phosphors is the sphere like. The effects of the stirring and sintering temperature on the morphology of Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+}/Eu{sup 2+},Mn{sup 2+} phosphors have been investigated. The photoluminescence spectra of Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+} and Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+},Mn{sup 2+} phosphors showed that the Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+} phosphors can be excited by 345 nm and exhibit blue emission around 421 nm and the Sr{sub 2}P{sub 2}O{sub 7}:Eu{sup 2+},Mn{sup 2+} phosphors can be excited by 355 nm andmore » exhibited the emission around 420 nm and 578 nm showing the white light.« less
