Environmental-friendly yellow pigment based on Tb and M (M=Ca or Ba) co-doped Y2O3

A yellow inorganic ceramic pigment with general formula Y1.86−xMxTb0.14O3−x/2 (M=Ca and/or Zn) with x=0.06, 0.32 and 0.64 were synthesized by a modified Pechini method. XRD, SEM and HRTEM/EDX analysis showed the formation of solid solution at 1300°C when x=0.06 and 0.32. The best b* yellow coordinat...
