Abstract

C60 -coupled Β-Fe Si2 nanocomposite structures were fabricated and their photoluminescence (PL) properties were investigated. The nanocomposites exhibit a pinned PL peak at 570 nm and a band edge at ∼370 nm. Spectral analyses suggest that the pinned PL behavior is closely related to both the Β-Fe Si2 nanocrystals and the coupled C60. A band-mixing model based on the direct and indirect gaps in a nanoenvironment consisting of mainly Β-Fe Si2 nanocrystals and C60 is proposed and used to derive the electronic states. Good agreement is achieved between the theoretical calculation and experimental results. © 2006 American Institute of Physics.
