In this study, synthesis of copper nanoparticles and effect of the reaction conditions on the particle size were investigated. The copper nanoparticles were synthesized and stabilized in a narrow temperature range in the presence of polyvinylpyrrolidone under nitrogen atmosphere. Reaction temperature and concentration ratio of the reducing agent to the precursor (R/P) as two main conditions i...
