Executive Summary : | The proposal aims to prepare small, magic size colloidal Quantum dots (QDs) and their core/shell structure of various QDs of the (II-VI) group. It demonstrates a method to continuously tune the radiative emission lifetime by varying the density of electronic states involved in the emission process. The unique composition-dependent electronic structure of various II-VI semiconductor QDs makes them a fascinating element in the semiconductor industry for sensing, energy harvesting, and imaging applications. The ability to control the uniformity of size, shape, and composition crystal structure and surface properties of the nanocrystal is essential for uncovering their intrinsic properties unaffected by sample heterogeneity. A rigorous understanding of the properties of individual nanocrystals will enable the design and building of novel electronic, magnetic, and photonic devices and other functional materials based on these nanostructures. The demand for QDs-based technology has increased due to the increasing demand for miniaturized technology. The QDs market was valued at $316 million and is expected to reach $5,040 million in 2020. The current market value is expected to rise up to USD 26.4 billion by 2028. Improving government expenditure for research and development activities can decrease manufacturing costs of QDs-based materials. QDs are used in sensing, solar cell, and fluorescent levels in biological applications, as well as TV and LCD display manufacturers due to their better color yielding capacity. Additionally, QDs can detect heavy metal impurities in ecological systems, minimizing their adverse effects on ecosystems and living organisms. |
