a PL profiles of the Cu(I)-based cluster scintillators under excitation at optimized wavelengths. b A CIE chromaticity coordinate diagram and corresponding photographs showcasing the as-prepared Cu(I)-based cluster scintillators under the excitation conditions. c Integrated PL intensity variation with temperature ranging from 80 to 320 K. d RL spectra observed under X-ray irradiation (operational conditions for X-ray source: 50 kV, 80 μA). e Comparative analysis of RL intensities between the Cu(I)-based cluster scintillators and commercially available scintillators YAP:Ce and PWO. Note that all measurements were subjected to X-ray irradiation at the same dosage. f Temperature-dependent RL spectra of the CDSCI scintillators from 80 to 320 K under X-ray irradiation (operational conditions for X-ray source: 50 kV, 80 μA).
