Abstract
Kajian ini bertujuan untuk menilaikesan terdop dan koterdop keatas sifat sifat termoluminisens bagi sampel kaca zink borat silika (ZBS).Tiga jenis kaca disediakan dengan menggunakan kaedah tradisional, iaitu, teknik pencairan pelindapkejutan dan berasaskan kepada: komposisi takterdop (ZBS), (90-x)ZnO-xB2O3-10SiO2 yang mana x= 30, 35, 40, 45, 50 mol%, komposisi terdop (45-x) ZnO-45B2O3-10Si2O-xCu2O yang mana 0.002 ≤ x ≤ 0.1mol% dan komposisi koterdop (44.995-y)ZnO-45B2O3-10Si2O-0.005Cu2O-ySnO2 yang mana 0.05 ≤ y ≤ 0.5mol% telah dihasilkan.
The aim of this study is to evaluate the impacts of doping and co-doping on the thermoluminescence properties of zinc borate silica (ZBS) glass samples. Three types of glasses were prepared by the traditional melt quenching technique: undoped composition (90-x)ZnO-xB2O3-10SiO2 where x= 30, 35, 40, 45, 50 mo l%, doped composition (45-x)ZnO-45B2O3-10Si2O-xCu2O where 0.002 ≤ x ≤ 0.1 mol% and codoped composition (44.995-y)ZnO-45B2O3-10Si2O-0.005Cu2O-ySnO2 where 0.05 ≤ y ≤ 0.5mol%. The size of the SnO2 nanoparticles used as codopedglass sample is around 22-31 nm. All the samples were confirmed to be amorphous using x-ray diffraction analysis.
