Why does a metal ion enhances the fluorescence of gold nanocluster upon interaction? is it because of ligand to metal metal charge transfer?. Why it should enhance fluorescence rather just forming a complex?. This effect is not specific to transition metal ion I have observed in both d and p orbital?

Make sure that you don't mix up fluorescence with phosphorescence. Phosphoresce is a spin-forbidden process, and is enhanced by heavy metal atoms (ions) due a strong Spin-Orbit Coupling (SOC) induced, thus relaxing the spin-forbiddenness.
