Abstract

Nanocrystallization processes of inorganic and biological materials yield a wide range of electrical, optical, and structural properties. This process focuses specifically on the potential of certain elements as fluorophores and unique host materials. These elements have unique properties, especially luminescence, which depends on their size. It occurs when impurities are added to the framework that limit quantum effects. The results of innovative research on the thermoluminescence (TL) properties of nanostructured materials are very promising. In this work, we aim to create high-performance materials to improve radiation exposure measurement instruments. In this paper, we report on the thermoluminescent properties of self-agglomerated CaSO4:Samarium (Sm) samples prepared using an environmentally friendly coprecipitation method. Unlike conventional techniques, no additional binder is required to create solid CaSO4:Sm samples. When subjected to beta particle irradiation, these materials exhibit peak TL intensity at 490 K at a heating rate of 4.8 K/s. It exhibits twice the sensitivity of the TLD-100 dosimeter already on the market. Additionally, the minimum detection level for these samples was found to be less than 0.71mGy.The investigation shows that computerized glow curve decomposition, as part of the residual emission curve fitting approach created by McKeever, shows that the emission curve is composed of four separate TL peaks exhibiting intermediate-order motion.
