A transparent hybrid metal halide glassy scintillation screen for high-resolution fast neutron radiography.

ABSTRACT: Fast neutron radiography offers exceptional penetration for high-density and bulky objects, yet its resolution is hindered by light scattering in conventional scintillators and screen fabrication techniques. To address this, here, we develop a transparent glassy Mn-based hybrid metal halide scintillation screen, (BTPP)_1.8(HTPP)_0.2MnBr₄ (BTPP⁺ = butyltriphenylphosphonium, HTPP⁺ = heptyltriphenylphosphonium), leveraging temperature-dependent ordered-disordered transitions. The large-area screen boasts >70% visible light transmittance (500-800 nm), a high photoluminescence quantum yield (~85.54%), and threefold higher light output than commercial ZnS (Ag): PP screens. With a spatial resolution of 5 lp mm^-1, it surpasses existin
