Abstract

Al₂O₃ changes from transparent to a range of intense colours depending on the chemical impurities present. In blue sapphire, Fe and Ti are incorporated; however, the chemical process that gives rise to the colour has long been debated. Atomistic modelling identifies charge transfer from Ti(iii) to Fe(iii) as being responsible for the characteristic blue appearance.
