Viorel Melnig, Mircea-Odin Apostu, Neculai Foca Cadmium Selenide Nanoparticles Synthesis in Water-Soluble Polymer System


Abstract:
Water soluble cadmium selenide (CdSe) nanoparticles were chemically obtained by polymer assisted synthesis at 70 Celsius degree from aqueous solution, using Cd(CH3COO)2·2H2O or Cd(NO3)2·4H2O as cadmium source and H2SeO3 as selenium source. The clustering of CdSe nanoparticles synthesized in poly(amidehydroxyurethane) matrix was clearly revealed by X-ray diffraction and Atomic Force Microscopy films studies. The obtained CdSe nanocrystallites have hexagonal symmetry with an average dimension of 25 nm. The Fourier Transform Infrared spectra show the interaction between the nanoparticles and urethane carbonyl and C - O - C etheric groups of polymer. The dimension of CdSe - polymer entities in water solution was explored by Laser Diffraction method and confirmed the capping of CdSe nanoparticles by the polymer. Keywords: CdSe, nanoparticles, polymer assisted synthesis, structural characterization
