Preparation and Optical Absorption of Zircons, Co-Doped with Vanadium and
Rare Earth Elements. — Single crystals of ZrSiO4:Pr,V and ZrSiO4:Tb,V are pre02- 011 pared
by heating mixtures of activated oxides ZrO2 and SiO2 together with V2O5 and
Pr6O11 or Tb4O7, resp., using Li2O·7MoO3 as a flux (1240 °C, 10 h). The additional rare
earth ions incorporated change the colors of the samples from blue (ZrSiO4:V) to pink
and to yellow-green for the (Pr/V) and (Tb/V) co-doped zircons, respectively. The correlation of the color shift to the size of the rare earth element offers the opportunity for
a specific development of new pigments by controlled co-doping of zircon-blue. —
