Abstract

Monodisperse 3.1 nm Ag2Te NCs show a sharp optical absorption feature at 1154 nm with a large linear temperature dependence and the photoconductive response consistent with semiconducting character in Ag 2Te NCs. The wavelength of the resonance is within the window of transparency for biological tissue making it a potential in vivo temperature marker or transducer for in situ heating with deep-penetrating near-infrared radiation.
