“…The defects based upon Eu 2+ 2+ , Ca 2+ and Ba 2+ ) phosphors have the highest luminescence intensity and longest afterglow time [11][12][13][14] . Recently, MAl 2 O 4 doped with Eu 2+ and Dy 3+ ions as long afterglow phosphor, has been well accepted in biological sensing, plastic, coating, glass, textile, solar cell fields [15][16][17][18][19][20][21] .…”

The long afterglow fluorescent material of M 1−3x Al 2 O 4 :Eu 2+ x /Dy 3+ 2x (M 2+ = Sr 2+ , Ca 2+ and Ba 2+) phosphors are successfully synthesized by calcining precursor obtained via co-precipitation method at 1300 o C for 4 h with reducing atmosphere (20% H 2 and 80% N 2). The phase evolution, morphology and afterglow fluorescent properties are systematically studied by the various instruments of XRD, FE-SEM, PLE/PL spectroscopy and fluorescence decay analysis. The PL spectra shows that the Sr 1−3x Al 2 O 4 :Eu 2+ x /Dy 3+ 2x phosphors display vivid green emission at ∼519 nm (4f 6 5d 1 →4f 7 transition of Eu 2+) with monitoring of the maximum excitation wavelength at ∼334 nm (8 S 7/2 → 6 I J transition of Eu 2+), among which the optimal concentration of Eu 2+ and Dy 3+ is 15 at.% and 30 at.%, respectively. The color coordinates and temperature of Sr 1−3x Al 2 O 4 :Eu 2+ x /Dy 3+ 2x phosphors are approximately at (∼0.27, ∼0.57) and ∼6700 K, respectively. On the above basis, the M 0.55 Al 2 O 4 :Eu 2+ 0.15 /Dy 3+ 0.3 (M 2+ = Ca 2+ and Ba 2+) phosphors is obtained by the same method. The PL spectra of these phosphors shows the strongest blue emission at ∼440 nm and cyan emission at ∼499 nm under ∼334 nm wavelength excitation, respectively, which are blue shifted comparing to Sr 1−3x Al 2 O 4 :Eu 2+ x /Dy 3+ 2x phosphors. The color coordinates and temperatures of M 0.55 Al 2 O 4 :Eu 2+ 0.15 /Dy 3+ 0.3 (M 2+ = Ca 2+ and Ba 2+) phosphors are approximately at (∼0.18, ∼0.09), ∼2000 K and (∼0.18, ∼0.42), ∼11600 K, respectively. In this work, long afterglow materials of green, blue and cyan aluminates phosphors with excellent properties have been prepared, in order to obtain wide application in the field of night automatic lighting and display.
