a Schematic of the light yield measurement system with an integrating sphere. b RL spectra of CsI:Tl single crystal and optimized Mn15%. (c) Comparison of light yields of CsI:Tl, Cs3Cu2I5 and optimized Cs3Cu2I5:Mn. d RL intensity of Cs3Cu2I5 and Mn15% versus temperature at an ultra-large range of 77-433 K. RL stabilities of Mn15% against e heating/cooling cycling and f long-term operation at room- and high temperature. The inset shows the stability measurement of CsPbBr3 nanocrystals under the same dose rate.
