Combination of inorganic nanocrystals (NCs) and organic molecules into composites have shown a variety of novel optical and electronic properties. Many of these properties arise from the inter-phase energy transfer from the excited NCs to a semiconducting matrix.
In this hot paper, Nakanishi and co-workers report the fabrication of a composite material of CdSe NCs embedded in an alkylated room temperature liquid C60 derivate. The photoelectrochemical and optical properties of the composite are investigated. It is found that the optical properties can be tuned by selection of the NC phase. Electronic band alignment between the NCs and the C60 matrix enable inter-phase charge transfer, resulting in a long-lived charge transfer state. The composite shows potential for use in sensing applications and photoelectrochemical processes.
