AbstractBlue phosphors Ca1-xAl2O4: xEu(2+) were prepared by high temperature solid-state method. Their structure, morphology and luminescent properties were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) and fluorescence spectroscopy. The effect of different amounts of fluxing agent H3BO3 on structure, morphology and luminescent properties of blue phosphors Ca1-xAl2O4: xEu(2+) luminous intensity caused by different amount of H3BO3 was also investigated. The amount of H3BO3 doped Ca1-xAl2O4: xEu(2+) in optimal luminous intensity had been determined. The results showed that both the excitation and emission spectra of samples were all broad bands, and that the peak of emission spectra was near 442 nm, which was corresponding to the 4f(6)5d -> 4f(7) transition of Eu2+ illuminating blue light. Ca1-xAl2O4: xEu(2+) (x = 3.5 mol%) could be gained with good morphology and the best luminous intensity when H3BO3 mass ratio was 0.5 wt%. (C) 2013 Elsevier GmbH. All rights reserved.
