Modern microscopic and surface analysis techniques can be used to get a better understanding of the pigment particles. In the case of a host pigment lattice such as the DR pigments, there is the question about the uniformity of the dopants throughout the particles. Some preliminary studies on some DR pigments indicate that the homogeneity of the dopants in a particle is dependent on the synthesis technique used. Some samples exhibited concentration gradients of the dopants across a sliced particle while others did not. For numerous reasons, great caution is needed before drawing definitive conclusions from the data.
