Abstract The preparation of GdVO4:Bi3+ ceramics is indicated. Bismuth shows a strong tendency to evaporate during the sintering process. Time-resolved emission spectroscopy shows for sufficiently low Bi3+ concentrations subsequently: blue VO 4 3− emission with a decay time corresponding to the transfer rate (106 s−1), yellow VO 4 3− −Bi3+ emission, rare-earth impurity emission and VO 4 3− −Bi3+ afterglow.
