Effect of gamma irradiation on microstructure of the layered Ge 0.995Nd0.005S

X-ray analysis of layered [Formula: see text] crystal has been investigated before and after gamma irradiation. Single crystal [Formula: see text] was irradiated with a [Formula: see text] gamma source which had an energy of 1.33 MeV. The dose rate was [Formula: see text] and the absorption dose was from 1 kGy up to 30 kGy. The thermogravimetric analysis, differential scanning calorimetric, differential thermogravimetric and differential thermal analysis were performed on the samples. The thermodynamic analysis was evaluated for the thermally stable temperature range for unirradiated and irradiated [Formula: see text] compound. The results showed the splitting of GeNdS sample in the manner [Formula: see text] at the temperature range of [Formula: see text] which leads to mass reduction by 0.29%.
