中文摘要	calcium lanthanide oxyborate doped with rare-earth ions lnca(4)o(bo3)(3):re3+ (lncob:re, ln = y, la, gd, re = eu, tb, dy, cc) was synthesized by the method of solid-state reaction at high temperature. their fluorescent spectra were measured from vacuum ultraviolet (vuv) to visible region at room temperature. their excitation spectra all have a broadband center at about 188 nm, which is ascribed to host absorption. using dorenbos' and j phi rgensen's work [p. dorenbos, j. lumin. 91 (2000) 91, r. resfeld, c.k. j phi rgensen. lasers and excite states of rare earth [m], springer, berlin, 1977, p. 45], the position of the lowest 5d levels e(ln,a) and charge transfer band e-ct were calculated and compared with their excitation spectra.eu3+ and tb3+ ions doped into lncob show efficient luminescence under vuv and uv irradiation. in this system, ce3+ ions do not show efficient luminescence and quench the luminescence of tb3+ ions when tb3+ and ce3+ ions are co-doped into lncob. gdcob doped with dy3+ shows yellowish white light under irradiation of 254 nm light for the reason that gd ions transfer the energy from itself to dy.
