摘要: A B S T R C Konjac glucomannan acrylates (KGM-AA) were used as soft templates to prepare the CdS nanoparticles. The structure and properties of nanoparticles characterized evaluated with XRD, TEM, HRTEM, TGA, UV–vis, Raman spectrum, optical limiting nonlinear analyses (Z-scan technique), respectively. It was interesting find that nanosized particles successfully grew in situ uniformly dispersed KGM-AA their size density could be effectively controlled by varying feed ratio Cd 2+ /KGM-AA. When is up 17.47% (wt%), material exhibits best performance threshold 367 mJ/cm 2 , good absorption coefficient (a2) 6.6023 � 10 cm W 1 refractive index (n2) 1.27 4 /GW. performances increase content composites. mechanism mainly originated from self-focusing behavior
