dc.description.abstractThe contents embodied in this thesis is divided into seven chapters. Chapter 1 is an introductory chapter which gives a concise and lucid introduction to the field and reports the major scientific contributions relevant to metal Nanoclusters. The introductory chapter represents an overview of the synthesis procedures, photo-physical properties, factors affecting its photo-physical properties and applications of these metal nanoclusters to diverse fields. Chapter 2 provides a detailed description of the material and methods used throughout the thesis. Chapter 3 describes synthesis of a biocompatible DTT (Dithiothreitol)-reduced LYS(Lysozyme) capped silver nanoclusters(AgNCs) and its application for selective and sensitive detection of Cu2+ and VB12. Detailed detection mechanism was studied. These AgNCs were also able to detect Cu2+ and VB12 inside live cells as well. Chapter 4 describes synthesis of a DTT reduced BSA(Bovine Serum Albumin) capped dual-emissive AgNCs and its application for selective and sensitive ratiometric detection of Cu2+ and IO4-. Detailed detection mechanism was studied. Chapter 5 describes a top-down synthetic approach to synthesize time-controlled two differently emissive copper nanoclusters (green and blue CuNCs) from a non-luminescent copper nanoparticles(CuNPs). Later, blue emissive CuNCs were utilized for detection of Fe3+ and GSH(Glutathione) via fluorescence turn-off-on mechanism. Detailed detection mechanism was studied. Chapter 6 reports two different strategies to produce AIDF (Aggregation induced delayed fluorescence)-based luminescent materials at room temperature from GSH-capped CuNCs by (1) simply modifying the solvent environment and (2) introducing of gadolinium (Gd3+) ions. Detailed analysis were investigated to reveal the generation mechanism of these AIDF properties. Further, Gd3+ induced AIDF of GSH-CuNCs were utilized to selectively detect Cr+6 ions. Chapter 7 provides a concise summary with future prospects.
