摘 要：New phosphors Sr2 Zn Si2O7: M（M=Mn2+, Tb3+） were synthesized through solid-state reaction, and their photoluminescent properties under UV and VUV region were investigated. The results showed that Sr2 Zn Si2O7:Mn2+ emitted green light with the strongest emission peak centered at 525 nm, and its quenching concentration under 254 and 147 nm excitation occurred at x = 0.08 and 0.06, respectively. Sr2 Zn Si2O7: Tb3+ emitted green light with the strongest emission peak centered at 541 nm, and its quenching concentration under 254 and 147 nm excitation also appeared at y = 0.25. At 147 nm excitation, the emission intensities of Sr2Zn0.94Si2O7: 0.06Mn2+ and Sr1.75 Zn Si2O7: 0.25Tb3+ phosphors were 54% and 36% of that of Zn1.96 Si O4:0.04Mn2+, respectively. And their decay times（τ1/e） were about 3.18 ms and 3.9 ms, respectively.
