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

Figure 5

The structural refinement patterns of BaTiO3 (sample A) 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 the theoretical curves. In this refinement, the coefficients of reliability were = 13.21%, = 16.25%, and = / = 1.23.
