中文摘要	the pb2+ luminescence in a series of silicate oxyapatites me(2)(y, gd)(8)(sio4)(6)o-2, me(4)y(6)(sio4)(6)o (me = mg: ca, sr) is reported and discussed in relation to the crystal structure. the maximum wavelengths of the excitation (s-1(0)-p-3(1)) and emission (p-3(1)-s-1(0)) bands of pb2+ are independent of the mc:y ratio (2:8 or 4:6) but they have lower energies in mgy-oxyapatites than in cay- and sry-oxyapatites. the stokes shift of pb2+ luminescence amounts to 11 100 to 11 400 cm(-1): which does not depend strongly on the host composition. there exists a mutual energy transfer between pb2+ and gd3+ in sr2gd8(sio4)(6)o-2. at last, the dependence of the energy transfer efficiency of pb2+-sm3+, tb3+: dy3+ in sr-2(la: gd)(8)(sio4)(6)o-2 and ca-2(y, gd)(8)(sio4)(6)o-2 on their doping concentrations was studied in more detail.
