Rare earth-doped luminescent materials typically emit characteristic fluorescence, but achieving non-characteristic emissions remains challenging. Here, the authors report unique blue emissions from ytterbium- and erbium-doped organic-inorganic metal halides, demonstrating high water resistance and a ~ 90% quantum yield in solution, highlighting their potential as liquid-phase X-ray scintillators
