| 英文摘要 | Three rare earth borosilicate oxyapatites, re5si2bo13 (re = la, gd, y), were synthesized via wet chemical method, of which re5si2bo13 (re = gd, y) were first reported in this work. in the three oxyapatites, [bo4] and [sio4] share the [to4] tetrahedral oxyanion site, and re3+ ions occupy all metal sites. the differential scanning calorimetry-thermo gravimetry measurements and high temperature powder x-ray diffraction pattern revealed a vitrification process within 300-1200 degrees c, which was due to the glass-forming nature of borosilicates. from the vuv excitation spectra of eu3+ and tb3+ in re5si2bo13, the optical band gaps were found to be 6.31, 6.54 and 6.72ev for re5si2bo13 (re = la, gd, y), respectively. the emission and excitation bands of eu3+ and tb3+ are discussed relating with their coordination environments. among the three hosts, y5sibo13 would be the best for eu3+ and tb3+-doped phosphors.
