Synthesis and Luminescence Property of Sr₃Al₂O₆:Eu³⁺ Red Phosph or Prepared by Co-Precipitation Technique

Abstract:

Sr₃Al₂O₆:Eu³⁺ red phosphor was synthesized by co-precipitation and investigated their crystal structures and luminescent properties in detail. EuCl₃ was used as rare earth sources to replace Eu₂O₃, which saving cost significantly. X-ray diffraction(XRD) and scanning electron microscopy (SEM) result indicated that the as-prepared phosphors was calcined at 1150 ^oC for 2h crystalized in cubic phase with space group of Pa-3 and uniform morphology. The average diameter of the phosphors were 1.8um. Excitation spectrum and emission spectrum results shows when Boric acid was added 3wt% and Eu³⁺ was added x=0.04((Sr_1-xEu_x)₃Al₂O₆), the red emission of Eu³⁺ centers was shown at peak of 611nm under near ultraviolet excitation with wavelength of 393nm. The emission spectrum was line spectrum. Luminous intensity achieved the optimum. The thermal quenching experiments indicated that it had thermal stability in the temperature of 20 ^oC -80 ^oC.
