Crystalline materials properties

WebCertain crystalline materials display a property called thermoluminescence (TL) that can be exploited for dosimetry. When such a crystal is irradiated, a portion of the absorbed energy can be stored in the lattice and recovered later in the form of visible light emission if the material is heated. WebCrystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized …
