Fig. 3From: Microstructural, Magnetic, and Optical Properties of Pr-Doped Perovskite Manganite La0.67Ca0.33MnO3 Nanoparticles Synthesized via Sol-Gel ProcessTEM images of the (La0.6Pr0.4)0.67Ca0.33MnO3 nanoparticles post-annealed at a 700 °C, b 800 °C, c 900 °C, and d 1000 °C for 5 h. Insets in (a–d) are the corresponding selected area electron diffractions taken from lots of (La0.6Pr0.4)0.67Ca0.33MnO3 nanoparticles, respectively. The indices are labeled based on the pseudo-cubic perovskite structure. e–f HRTEM images of the (La0.6Pr0.4)0.67Ca0.33MnO3 nanoparticle post-annealed at 700 and 900 °C for 5 h. Inset is the FFT pattern of the HRTEM imagesBack to article page
