Na-alloy tailored 3D/0D metal halide heterostructures enabling efficient charge transfer for color-integrated white scintillators

Synthesis and characterization of 3D/0D heterostructures

As presented in Fig. 1a and Supplementary Fig. 2, Cs₂NaLuCl₆(Sb) has a typical 3D double perovskite crystal structure, where [LuCl₆]³⁻ octahedron and [NaCl₆]⁵⁻ octahedron are separated…
