Abstract Colloidal CuInS 2 quantum dots have been synthesised and characterised using absorption and photoluminescence spectroscopy, X-ray diffraction, inductive-coupled plasma atomic emission spectroscopy and thermogravimetric analysis. The ultrafast charge dynamics of these dots have been studied using transient absorption spectroscopy. Cooling of hot photo-generated carriers to the band edge occurred within 3–5 ps. Significant de-population of the band-edge was found to occur on a sub… CONTINUE READING
