In recent years, synthesis of metal nanoclusters and deep understanding of many fundamental properties of the nanoclusters have drawn considerable attention owing to their multimodal application in light harvesting, hydrogen production, optical sensor, drug delivery and cancer therapy. Intriguing molecular-like properties, such as HOMO–LUMO, d-sp or sp-sp transitions, quantized charging and strong luminescence are often observed in metal nanoclusters. The optical properties of metal nanoclusters can be tuned by changing the number of metal atoms, surface functionality and heteroatom doping. However, the fundamental studies on tuning of these parameters and their effect on the photophysical properties of the metal nanoclusters are
still in the embryonic stage. In this context, current thesis describes the development of synthesis
methods for highly luminescent metal nanoclusters and metal nanoclusters based functional
materials, which can fabricate efficient nanomaterials to find out potential applications in optical sensing, light harvesting systems and other photo driven devices.Research was conducted under the supervision of Prof. Amitava Patra of the Materials Science division under SPS [School of Physical Sciences]Research was carried out under CSIR fellowshi
