摘要
Embodiments of compositions comprising materials satisfying the general formula AM1−xM′xM″yO3+y are disclosed, along with methods of making the materials and compositions. In some embodiments, M and M′ are +3 cations, at least a portion of the M cations and the M′ cations are bound to oxygen in trigonal bipyramidal coordination, and the material is chromophoric. In some embodiments, the material forms a crystal structure having a hexagonal unit cell wherein edge a has a length of 3.50-3.70 Å and edge c has a length of 10-13 Å. In other embodiments, edge a has a length of 5.5-7.0 Å. In particular embodiments, M′ is Mn, and Mn is bonded to oxygen with an apical Mn—O bond length of 1.80 Å to 1.95 Å. In some embodiments, the material is YIn1−xMnxO3, x is greater than 0.0 and less than 0.75, and the material exhibits a surprisingly intense blue color.
