Up-scalable synthesis of size-controlled copper ferrite nanocrystals by thermal treatment method

Close-packed cubic copper ferrites (CuFe2O4) nanoparticles were synthesized using an effective thermal-treatment method directly from an aqueous solution containing copper and iron nitrates as metal precursors and poly(vinyl pyrrolidone) as a capping agent. The FTIR spectra of the calcined samples r...
