چکیده انگلیسی
Monodispersed spherical CdS nanoparticles stabilized in PVA solution were synthesized by the gamma radiolytic method and found the average particle size increased from 12 to 13Â nm with the increment of dose from 10 to 40Â kGy. The XRD results show that it has crystalline planes of cubic structure with crystal lattice parameter of 5.832Â Ã
. The optical reflectance revealed a band-edge of CdS nanoparticles at about 475Â nm and the reflectance wavelength red shifted with increasing dose due to increasing particle size. The thermal conductivity of CdS/PVA nanocomposites measured by the transient hot wire method that revealed a decrement of the thermal conductivity with an increase of dose caused by effect of radiation on crystallinity of the polymer structure.
