Developing a novel method to synthesize highly dispersed nanosemiconductor materials is a major challenge in expanding the application field of luminescent materials. The study showed that the content of acrylamide and methylene diacrylamide significantly affects the properties of CeO2 nanoparticles synthesized using a modified polyacrylamide gel method.
Developing a novel method to synthesize the highly dispersed nanosemiconductor materials is the major challenge in the expand the application field of luminescent materials. A modified polyacrylamide gel method has been used to synthesize the CeO2 nanoparticles by using cerium sulfate as metal source. The method makes full use of exothermic reaction of cerium sulfate in the precursor solution to polymerize acrylamide and methylene diacrylamide to obtain gel. The phase purity, particle size, optical properties, and photoluminescence properties of CeO2 nanoparticles demonstrate the strongly dependent behavior of acrylamide and methylene diacrylamide (AMMD) content. The synergistic effect of oxygen vacancy concentration, impurity functional group, and surface adsorbed oxygen leads to high photoluminescence performance of CeO2 nanoparticles prepared with the AMMD content of 0.3.
