Title: Controlled synthesis and luminescent properties of Eu{sup 2+}(Eu{sup 3+}), Dy{sup 3+}-doped Sr{sub 3}Al{sub 2}O{sub 6} phosphors by hydrothermal treatment and postannealing approach

Abstract

In this work, Sr{sub 3}Al{sub 2}O{sub 6}: Eu{sup 2+} (Eu{sup 3+}), Dy{sup 3+} phosphors have been prepared by hydrothermal treatment and subsequently postannealing approach, using Sr(NO{sub 3}){sub 2}, Al(NO{sub 3}){sub 3}.9H{sub 2}O, and CO(NH{sub 2}){sub 2} as starting materials. The as-obtained phosphors were characterized by means of XRPD, FESEM, and PL techniques. In addition, many reaction parameters were studied in detail, including the initial mole ratios, hydrothermal reaction temperature, calcination temperature and calcination atmosphere. Remarkably, two scientific merits exist herein: Sr{sub 3}Al{sub 2}O{sub 6}: Eu{sup 2+} (Eu{sup 3+}), Dy{sup 3+} phosphors can be selectively obtained in a reducing atmosphere (H{sub 2}/Ar, 20%+80%) and in air, respectively; adding certain amount of sodium citrate can alter the shape and size of Sr{sub 3}Al{sub 2}O{sub 6}: Eu{sup 2+} (Eu{sup 3+}), Dy{sup 3+} phosphors in essence. Besides, the luminescent properties of Sr{sub 3}Al{sub 2}O{sub 6}: Eu{sup 2+} (Eu{sup 3+}), Dy{sup 3+} phosphors were studied by excitation spectra, emission spectra and decay curves. - Graphical abstract: We present a simple and efficient hydrothermal treatment and subsequently postannealing approach to prepare Sr{sub 3}Al{sub 2}O{sub 6}: Eu{sup 2+} (Eu{sup 3+}), Dy{sup 3+} phosphors on a large scale.
