Abstract

In this paper

a series of broadband-emitting and tunable Ba

∶

(0.01≤

≤0.09) phosphors were successfully synthesized by the high-temperature solid-phase method. The results of X-ray diffraction

scanning tunnel electron microscopy and EDS mapping proved that we synthesized aluminate phosphor with pure phase and uniform element distribution. Under the excitation of near-ultraviolet light wavelength of 361 nm

we found that the luminous intensity of Ba

∶

samples gradually increased and the luminous color of Ba

∶

samples gradually change from blue to cyan as the Ce

concentration increased. When

=0.05 mol

the luminescence intensity of the Ba

0.95

∶0.05Ce

sample reaches the maximum

and the fluorescence internal quantum yield is 30.8%. Steady-state spectroscopy and fluorescence lifetime results confirm that when the doped Ce

concentration is greater than 0.05 mol

the Ba

∶

sample undergoes concentration quenching

and the concentration quenching is mainly due to the energy transfer between adjacent Ce

-Ce

. The Ba

0.95

∶0.05Ce

sample exhibits a cyan emission with a spectral coverage of 365-650 nm

a main peak at 450 nm

and its full width at half maximum is 120 nm. The asymmetric broad emission band mainly originates from the two Ce

emission centers occupying the Ba1 and Ba2 sites in the host lattice. Simple dichromatic pc-WLEDs with UV excitation(

=365 nm)

full-visible-spectrum white light with adjustable color index and associated color temperature were prepared by mixing Ba

0.95

∶0.05Ce

with a commercial red phosphor. The Ba

0.95

∶0.05Ce

phosphor with broadband cyan luminescence developed in this work has potential applications in the field of full-spectrum lighting.
