Abstract:Herein, the gold nanoclusters/CaFe 2 O 4 nanospheres (Au NCs/CaFe 2 O 4 ) heterostructure as a novel electrochemiluminescence (ECL) emitter was developed. Excitingly, Au NCs/CaFe 2 O 4 displayed highly efficient and greatly stable ECL based on the newly defined electronaccelerator p-type semiconductor CaFe 2 O 4 NS-induced fast electron transfer; it solved one key obstacle of metal NC-based ECL emitters: sluggish throughcovalent bond electron transport kinetics-caused inferior ECL performance. Specifically, on… Show more
