A new aluminate host material Ca3ZnAl4O10 doped with Eu2+ was prepared by a high-temperature solid-state reaction method,and a pure crystalline phase of Ca3ZnAl4O10 was confirmed with X-ray powder diffraction (XRD) measurement.The luminescent property was investigated with excitation and emission spectra.The phosphor could be excited by UV light from 220 nm to 400 nm and emitted a blue luminescence peaked at 450 nm,which corresponded to the 4f65d1→4f7 transition of Eu2+ ions.The dependence of luminescence intensities of Eu2+-doped Ca3ZnAl4O10 on the doping concentrations was investigated.The luminescence decay and the color coordinates were discussed in order to further investigate its potential applications for white light-emitting diode phosphors pumped by a near-UV chip.
