Till date, the emission has been reported from Mo\n                    <jats:sup>3+<\/jats:sup>\n                    \u2010doped into bulk host materials, in the powder or single crystalline forms. Here we report the synthesis of Mo\n                    <jats:sup>3+<\/jats:sup>\n                    doping in a colloidal nanocrystal (NC).

The challenges of poor solubility of molybdenum precursor and instability of low oxidation state of Mo\n                    <jats:sup>3+<\/jats:sup>\n                    in the reaction medium are overcome by a rational design of the synthesis. The resulting NCs have cubic shape with edge length \u223c9\u00a0nm, and oleylammonium ions as the predominant surface capping ligands. The colloidal synthesis enabled us to fabricate thin films of Mo\n                    <jats:sup>3+<\/jats:sup>\n                    \u2010doped NCs by spin\u2010coating technique.
