Abstract The luminescence of a number of vanadates is reported. The emission is assigned to the 3T1(t152e)→ 1A1(t16) and 3T2(t152e)→1A1 transitions. The 3T1(t152e) level appears to be the lowest exicted state of the vanadate group. The excitation is assigned to the 1A1(t16)→1T1(t152e) (the “Teltow” band) and 1A1(t16)→1T2(t152e) transitions. The position of the excitation bands is only slightly influenced by the host. The host-lattice dependence of the quenching temperature of the emission is discussed in terms of a configurational-coordinate model.
