Abstract

original image

Composite thin films of polyelectrolytes and fluorescent nanoparticles can be directly transfer-printed onto various substrates including indium tin oxide coated poly(ethylene terephthalate). The sequential transfer printing of thin films with controlled alignment introduces multicomponent patterns onto substrates, demonstrating possible practical device fabrication using functional polyelectrolyte multilayer composite thin films (see Figure).
