Abstract
The area of radiation protection has gained significant relevance due to the fast advancement of radiation technology and its utilization in scientific research. In order to meet the low doses of nuclear radiation, such as gamma (γ)-rays, development of great fineness, stable, and reliable sensors are required. The heterocyclic compounds known as metallophthalocyanines (MPcs) won considerable research interest owing to their exceptional thermal, chemical and photo-stability, and long wavelength absorption compatible with biological window, spreading their potential applications in technology and medicine. As a result, finding the ideal method for creating such molecules is always in the spotlight. In this work, we designed a novel and efficient microwave-assisted synthetic method for preparation of innovative sensor materials base on MPcs (M = Zn, Mn or Fe). A zinc phthalocyanine has been evaluated as model compound in preparing ZnPc/PVA composites as a new, effective chemical-based dosimeter for low-dose measurement of γrays within the dose range from 1-25 kGy. A microwave-enhanced synthetic approach has been evaluated as an impressive chemical-based dosimeter designer. A modest decrease in absorbance intensity, followed by color bleaching in the dose range of 1-25 kGy, enabled the preparation of ZnPc/PVA composites as fine, glossy surface films with impressive application in gamma-ray dosimetryTwenty-First Young Researchers’ Conference - Materials Science and Engineering: Program and the Book of Abstracts; November 29 – December 1, 2023, Belgrade, Serbi
