Abstract

Copper containing spinel‐type In2S3 nanocrystals were prepared by rapid pyrolysis (RP) from a single source inorganic‐organic hybrid molecular precursor with an initial Cu:In:S ratio of 1:9:16.5. The precursor was synthesized in a one‐step hydrothermal reaction with high yield. After a treatment of the precursor for 10 s at 1000 °C a powdered material was obtained. The X‐ray powder pattern exhibits broad reflections indicative for the spinel‐type and crystallites in the nanometer range, however, the positions of the reflections match well with different compounds of the In‐S and Cu‐In‐S systems. High resolution transmission electron microscopy (HRTEM) studies in connection with EDX analyses evidence the presence of cubic spinel‐type copper containing In2S3. Two such In2S3 phases coexist with one being copper poor and the other having a larger copper content. The coexistence of these two compounds is reflected by the Raman and UV/Vis spectra.
