New oxides showing an intense blue color based on Mn3+ in trigonal-bipyramidal coordination.
Substitution of Mn(3+) into the trigonal-bipyramidal sites of oxides with YbFe(2)O(4)-related structures produces an intense blue color because of an allowed d-d transition. This has been demonstrated utilizing a variety of hosts including ScAlMgO(4), ScGaMgO(4), LuGaMgO(4), ScGaZnO(4), LuGaZnO(4), and LuGaO(3)(ZnO)(2). The hue of the blue color can be controlled by the choice of the host.
