Dosimetric analysis of graphitic carbon nitride quantum dots exposed to a gamma radiation for a low-dose applications

In this study, graphitic carbon nitride quantum dots (g-C3N4QDs) were synthesized using different solvents, characterized, and then exposed to a gamma-ray source (137Cs) at irradiation doses of 0.1, 1.48, 2.05 and 3.25 Gy. The intensities of the emission bands progressively were attenuated as the received dose of gamma radiation increased. The changes were quantified with the help of a non-linear fit model. The material showed promising use as a dosimeter for low-dose radiation applications.PMID:35325648 | DOI:10.1016/j.apradiso.2022.110200
