Abstract

Cuprorivaite (CaCuSi4O10, also known as Egyptian blue) exhibits an exceptionally high emission quantum efficiency in the near-infrared region (λmax = 910 nm, ΦEM = 10.5%) and a long excited state lifetime (107 μs); these properties make it appealing for several applications in the fields of biomedical analysis, telecommunications and lasers.
