Abstract

original image

EuS and Ag2S colloidal semiconductor nanocrystals are observed to display optical properties characteristic of the corresponding bulk materials, yet have the desirable processing properties of colloidal nanocrystals. We envision that bulk nanoparticles will play a complementary role to quantum-confined structures as another building block for the development of new technologies.
