When the temperature reached about190∘C,combustion flame appeared.Figure 2 shows the observation of flame during the combustion of nitrate and fuel.After completion of combustion,the crude brown color powder was obtained . The obtained combustion product was annealed at 800∘C for 3hrs in a groove rolled muffle furnace. After completion of annealing, the furnace was cooled to room temperature by switching off the power. The annealed product was white in color and taken for characterizations. The phase identification and purity of the annealed materials were tested by powder XRD and FT-IR spectroscopy The photoluminescence(PL)property of the MgO powder sample was performed in a spectrofluorometer (ELICO SL 174) using 150 Watt Xenon Arc lamp as the excitation light source. The NIR spectrum of MgO powder was performed in a NIR Spectrophotometer (ELICO SL 153) using Quartz halogen lamp as the light source. The microstructural images and the elements present in the combustion-annealed MgO materials were performed in the scanning electron microscope, SEM (Jeol model; JSM-6390LV), attached with Energy Dispersive X-ray Analyzer(JED-2300).
