Synthesis and optical studies of GdCrO3 nanoparticles

Synthesis and optical studies of GdCrO3 nanoparticles: "

Abstract

Here we report for the first time, a detailed synthesis mechanism of GdCrO₃ nanoparticles using a surfactant-less hydrothermal method. We also report a detailed study of their structural and optical
properties. The selected area electron diffraction and powder X-ray diffraction studies of GdCrO₃ nanoparticles show pure phase and excellent crystallinity with average particle size around 50–60 nm. The structural analysis
indicates a distorted perovskite crystal structure with lattice parameter values of a = 5.3099 ± 0.0022, b = 5.51793 ± 0.00226, and c = 7.60426 ± 0.00315 Å. For the first time, we report the room temperature UV–vis, photoluminescence, FTIR, and X-ray photoelectron
spectroscopy results and their detailed analysis for GdCrO₃. These results provide optical signatures of the formation of GdCrO₃ where both Gd³⁺ and Cr³⁺ play dominant role in different frequency regions.
