Solid state chemistry is playing a vital role in the designing of advanced inorganic functional materials for electronics, magnetism, energy conversion, lasers, lighting, and phosphors, to name a few. New functional materials discovery research is frequently driven by a desire to use ‘materials by design’ concepts in the quest for finding better, greener and more efficient materials. However such research endeavor can occasionally lead to unexpected breakthrough discoveries in other interdisciplinary areas. This talk will describe our spectacular discovery of new class of highly durable intense color pigments based on rare earth transition metal oxides where transition metal cations occupy an unusual trigonal bipyramidal coordination that we were exploring for multiferroics. We have now leveraged this discovery to rationally design advanced inorganic oxide based pigments with desired color as well as other functionalities which are now commercialized by pigment industry.
