چکیده انگلیسی
SrZnO2:Eu3+ has been synthesized by solid-state reaction and its photoluminescence in ultraviolet (UV)–vacuum ultraviolet (VUV) range was investigated. The broad bands around 254 nm are assigned to CT band of Eu3+–O2−. With the increasing of Eu3+ concentration, Eu3+ could occupy different sites, which leads to the broadening of CT band. A sharp band is observed in the region of 110–130 nm, which is related to the host absorption. The phosphors emit red luminescence centered at about 616 nm due to Eu3+5D0→7F2 both under 254 and 147 nm, but none of Eu2+ blue emission can be observed.
