| dc.description.abstract | The investigation of SrTiO3 solution preparation by using of chemical reaction method has been done. The chemicals used are Strontium Carbonate (SrCO3) and Titanium Dioxide (TiO2), with the concentrations of each sample are 0,005 moles, 0,006 moles, and 0,007 moles, and the temperature differences are 600 oC, 700 oC, and 800 oC respectively. The number of samples made are six. The optical properties of SrTiO3 are investigated solution using some UV-Vis spectroscopy method. The results obtained from this study are some absorbance spectrums. The concentration 0,005 moles, 0,006 moles, and the concentration 0,007 moles before annealing at wavelength of 285 nm, 281 nm, and 282 nm have the same absorbance intensity which is 3,999 a.u. After annealing by a concentration 0,005 moles on a temperature of 600 oC, a concentration 0,006 moles on a temperature of 700 oC, and a concentration 0,007 moles on a temperature of 800 oC at wavelength of 279 nm, 277 nm and 279 nm turned out to have the same intensity of absorbance which is 3,150 a.u. So, the intensity of the absorbance materials before annealing is smaller than those materials after annealing. | en_US |
