Mn²⁺ induced significant improvement and robust stability of radioluminescence in Cs₃Cu₂I₅ for high-performance nuclear battery.

ABSTRACT: Fluorescent type nuclear battery consisting of scintillator and photovoltaic device enables semipermanent power source for devices working under harsh circumstances without instant energy supply. In spite of the progress of device structure design, the development of scintillators is far behind. Here, a Cs₃Cu₂I₅: Mn scintillator showing a high light yield of ~67000 ph MeV^-1 at 564 nm is presented. Doping and intrinsic features endow Cs₃Cu₂I₅: Mn with robust thermal stability and irradiation hardness that 71% or >95% of the initial radioluminescence intensity can be maintained in an ultra-broad temperature range of 77 K-433 K or after a total irradiation dose of 2590 Gy, respectively. These superiorities allow the
