Synthesis of new red-emitting single-phase europium oxycarbonate.
A fascinating one-pot solvent-, catalyst-, and template-free synthesis process to facilitate a single-phase crystalline hexagonal type-II luminescent Eu(2)O(2)CO(3) organization comprised of nanoplates is demonstrated. The thermolysis (700 degrees C) of europium acetate in a closed stainless steel reactor under autogenic pressure [approximately 3 MPa] yielded Eu(2)O(2)CO(3) superstructures. Powder X-ray diffraction, high-resolution transmission electron microscopy, and Raman measurements confirmed the structure. Fourier transform infrared spectroscopy, energy-dispersive spectrometry, and CHNS analysis verified the composition. Scanning electron microscopy corroborated the morphology of the new Eu(2)O(2)CO(3) compound, and the primary luminescence properties are accounted.
