Abstract
In this study, the structural properties of Urfa stone (US) doped with chromium oxide (Cr2O3) were investigated using X-ray diffraction (XRD) and FT-IR spectroscopy. The photoluminescence properties of US doped with varying amounts of Cr2O3 (5, 10, 20, 30, and 40%) were also investigated. US powder was obtained via grinding with an agate mortar, and Cr2O3 was then added as a dopant to the US powder. The samples were sintered at 1000 °C for 1 h. The XRD results of the US powder doped with Cr2O3 via mechanical alloying showed the presence of some crystalline phases: calcite (CaCO3) and eskolate (Cr2O3). Furthermore, it was found that calcium oxide (CaO) and tongbaite (Cr3C2) were also present in the sintered samples. The photoluminescence analysis results indicated that the emission and excitation bands of the US-Cr complex shifted to longer and shorter wavelengths in the solid state (non-aqueous media), respectively.
