Influence of Impurities on the Luminescence of Er3+ Doped BaTiO3 Nanophosphors

Figure 6

The structural refinement patterns of BaTiO3 (sample B) using X-ray powder diffraction data. Open red circles correspond to the experimental data ( ); solid black line is the calculated pattern ( ), while the blue line is the difference between the experimental and theoretical curves. In this case, = 13.79%, =18.19%, and = 1.32.
