摘要：

Investigations of the luminescence properties of LiSr2Y1-xEuxO4, LiSr2Y1-xTbxO4 and LiSr2Y1-xTmxO4 (0 less than or equal to x less than or equal to 1) at room temperature are reported. These samples were synthesized by a solid state reaction. The excitation spectra of Tb1+ emission in LiSr2Y1-xTb1O4 (0 less than or equal to x less than or equal to 1) consist of broad bands corresponding to a transition between the 4f(8) and 4f(7)5d(1) states of Tb3+. The maximum intensity is situated at about 318 nm. This is at a much longer wavelength than those of other Tb3+ doped phosphors. This is explained bq a large offset of the adiabatic potential curve of the 4f(7)5d(1) state. (C) 1998 Elsevier Science S.A.
