| Abstract: | 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 luminesce... |
