Paper doi abstract bibtex CsCu 2 I 3 CsCu 2 I 3 lead‐free nanocrystals (NCs) have recently garnered significant interest for their outstanding optical and scintillation characteristics, particularly for X‐ray imaging applications. In this study, CsCu 2 I 3 NCs are mixed with polydimethylsiloxane (PDMS) resin in the form of a pellet to protect against environmental factors such as moisture. The resulting sample exhibits a light yield of up to 2 ph keV −1 and an excellent energy resolution of 13% for γ‐ray excitation at 662 keV at room temperature. Additionally, the CsCu 2 I 3 NCs–PDMS resin shows no afterglow and has a negligible trap density. Herein, high stability at low irradiation intensities and reasonable stability at higher intensities are demonstrated. Moreover, the sample features a fast component scintillation decay times of 3.55 ns, which is slightly faster than that of (BZA) 2 PbBr 4 . This outcome possesses promising combination in designing lightweight and flexible hybrid PDMS‐based hybrid materials scintillators. These scintillation properties of CsCu 2 I 3 NCs–PDMS can be a promising candidate for affordable and flexible screens for X‐ and γ‐ray photon‐counting computed tomography.
