We investigated the broadband red emission from Cs4PbBr6 crystals observed under high-energy excitation using cathodoluminescence spectroscopy. The optical characteristics of this emission were clarified through spatial, spectroscopic, and time-resolved measurements, and the energy structure responsible for this emission is discussed.
