Abstract

Heterostructured multilayer films of two different nanocrystals have been successfully fabricated by layer-by-layer stacking of Ti0.8Co0.2O2 nanosheet and Fe3O4 nanoparticle films. UV–Vis spectroscopy and AFM observation confirmed the successful alternating deposition in the multilayer buildup proce...
