Preparation and characterization of a luminescent hybrid nanocomposite, ((n-C4H9)(4)N)(2)Mo6Br14@ZnO, is achieved by using a straightforward fabrication process. The hybrid nanocomposite can be applied both under organosol and solid-state conditions. PL experiments show that the intrinsic photophysical properties of the cluster anion [Mo6Br14](2-) are not affected by its inclusion in the ZnO organosol. The obtained nanocomposite can be applied as a versatile luminescent nanomaterial with emissions ranging from 430 to 850 nm.
