AB  - This work investigates the luminescence properties and energetic structure of emission centers created by NaCsisoelectronic impurities in a well-known CsI:Na scintillation crystal. Using synchrotron radiation excitation at 8K, high-resolution spectroscopic techniques were employed to probe the electronic transitions and luminescentdynamics within the crystal. The study reveals distinct emission bands that can be attributed to both self-trappedexciton (STE) states and excitons bound to NaCs and defect-related centers, with a clear separation between fastand slow decay components. These findings provide deeper insight into how the NaCs impurity alters theemission behaviour of the CsI host, including modifications to energy transfer and relaxation processes.
