Advances and Current Progress of Dopant Engineering on All‐Inorganic Halide Perovskites Toward High‐Performance Scintillating Materials [link]Paper  doi  abstract   bibtex   
ABSTRACT In recent years, metal halide perovskites have attracted significant interests due to their remarkable optoelectronic and scintillation properties, as well as the benefits of facile and low‐cost processing. All‐inorganic perovskites (AIPs) exhibit superior thermal stability and strong radiation absorption compared with hybrid organic–inorganic perovskites, positioning them as promising candidates for next‐generation scintillators. However, the presence of lead in most perovskite materials poses significant toxicity concerns, driving intensive efforts toward the development of nontoxic, lead‐free AIP alternatives. This review briefly outlines the recent developments of lead‐free AIPs, working principle, different synthesis methods, and scintillation properties associated with self‐trapped exciton (STE). We highlight dopant engineering strategy to favor the formation and efficient radiative recombination of STEs in low‐dimensional AIPs. Finally, we provide the future development direction to pave the way for high‐performance, next‐generation lead‐free AIP scintillators.
