| Abstract | The physical and optical properties of glass samples which manufactured using sugar cane ash were investigated. The chemicalcomposition of the sugar cane ash was first analyzed using an X-Ray fluorescence Spectrometer (XRF). The sugar cane ashsamples were sintered at di erent temperatures (400 C, 600 C, 800 C and 1000 C) under the same background conditions.Samples were produced with increasing concentrations of Cr2O3. It was found that the density and refractive index of the glasssamples was found to increase as a result of increasing the concentration of Cr2O3 in the sample. The absorption spectra of thesamples was measured using a UV-visible light spectrometer. The absorption peak was found to be at 640 nm. This was thoughtto be due to the transition 4A2g (F) --> 4T2g (F). This was in turn thought to be due to the Cr3+ ion in octahedral coordination withstrong tetragonal distortion. There was another absorption band that was observed at approximately 460 nm. This was thoughtto be due to the split components of the 6A1g(S) --> 4T2g (G) transition. Iron, in the Fe2+ state, exists in the glass in equilibriumwith the yellow ferric ion (Fe3+). The color coordinate in the glass samples were measured and showed good agreement withthe absorption spectra that was observed |
