Cu$_2$ZnSnS$_4$ (CZTS) thin films for three samples were prepared at the same deposition parameters by thermal evaporation method
at a vacuum pressure of 6.0×10$^{−5}$ Torr and investigated using irradiation technique. The films deposited were irradiated with the gamma
irradiation source (Cs-137) when activity = 1317.72 MBq, dose rate = 100.686 Gy/h for 300 and 600 Gy doses to study the influence
of gamma irradiation on the structural, morphological and optical properties of the films. X-ray diffraction (XRD), scanning electron
microscopy (SEM), energy-dispersive X-ray (EDX) and UV–V is were used to investigate the properties of the as-deposited and irradiated films.
X-ray diffraction (XRD) studies of the as-deposited and irradiated thin films revealed a kesterite structure with tetragonal lattices at a preferred
orientation along 2
