1. A process for producing inorganic fullerene-like (IF) metal chalcogenide nanoparticles, the process comprising:

  • (a) preparing a metal precursor vapor, selected from the group consisting of metal halide vapor, metal carbonyl vapor, organo-metallic compound vapor and metal oxyhalide vapor, in a separate evaporation chamber;

    (b) feeding the metal precursor vapor from said separate evaporation chamber into a reaction chamber to flow towards a reaction zone in said reaction chamber along a vertical path to interact with at least one chalcogen material in gas phase flowing towards said reaction zone in a vertical path in a direction opposite to that of the metal precursor vapor flow, and controlling temperature conditions in said reaction zone such as to enable the formation of inorganic fullerene-like (IF) metal chalcogenide nanoparticle product.
