Studies from Mansoura University Yield New Information about Nanoparticles (Impact of in situ preparation of CdS filled PVP nano-composite)

August 12, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Nanoparticles. According to news reporting out of Mansoura, Egypt, by NewsRx editors, research stated, "Cadmium sulfide nanoparticles filled polyvinyl pyrrolidone (PVP) were prepared by in situ wet chemical precipitation technique. X-ray diffraction (XRD), Fourier transforms infrared spectra (FTIR), transmission electron microscopy (TEM) and ultraviolet-visible (UV/Vis) were used to characterize the prepared nano-composites."

Our news journalists obtained a quote from the research from Mansoura University, "Density Function Theory (DFT) was used to approve the complexation process. XRD results indicate appearance of two peaks at about 28.1 degrees, 27.4 degrees corresponds to (101) and (002) planes which suggest hexagonal phase of CdS with lattice constants of 4.14, 6.72 angstrom in the polymeric matrix. UV/Vis spectra reveal that nano-composite films show quantum confinement effect. The absorption showed a shift toward the shorter wavelength (blue shift) with decrease in the concentration of Cd+ ions. Optical band gap and particle size were calculated and is in agreement with the results obtained from TEM data."

According to the news editors, the research concluded: "Transmission electron microscopy shows that the prepared CdS nanoparticles were dispersed and nearly uniform in diameter within the polymeric matrix."
