Abstract

Quartz sand (Quartz Sand-QS) is an abundant natural material in Indonesia, specifically in Huta Ginjang, North Sumatra Province. This material has great potential as a basic material for the development of glass systems for medical imaging (X-ray imaging) applications. Synthesis and preparation of Huta Kidney quartz sand-based glass medium and di-double doped phosphate glasses with Gd3+ and Eu3+ ions (PoCage) were performed for X-ray radiation scintillator applications. The composition of the glass system follows the chemical formula (15-x) QS-50P2O5-15CaO-10BaO-10gD2O3-xEu2O3 (where x = 0- 0.5- 1.0- 1.5- 2.0 mol.%). Samples were prepared using the melt-quenching technique at a melting temperature of 1300oC and a glass system with good homogeneity and transparency was obtained. The structural properties of the glass medium were observed by using XRD and FTIR to find out the diffraction patterns and clustering of network functions in the glass structure. Based on the results of observations it is known that the quartz sand glass medium of Huta Kidney and calcium phosphate di-double doping with Gd3+/Eu3+ ions (PoCage) has an amorphous structure which indicates that the properties of the medium after doped are intact as glass without any crystalline properties in it. In addition, the FTIR spectrum shows a variety of absorption bands, indicating the existence of functional bonds and clusters in the glass network.
