Nanocrystals are nanoparticles with crystalline structures that typically range from 1 to 100 nanometers in size. These tiny crystals possess unique optical, electronic, and mechanical properties that differ significantly from their bulk counterparts due to their high surface area to volume ratio and quantum mechanical effects at the nanoscale. The properties of nanocrystals can be finely tuned by altering their size, shape, composition, and surface chemistry, making them highly versatile for a wide range of applications. They are extensively used in fields such as electronics, for improving display screens and semiconductor devices; in medicine, for targeted drug delivery and enhanced imaging techniques; and in renewable energy technologies, such as in solar cells and energy-efficient lighting solutions. The controlled synthesis of nanocrystals is a critical area of research in nanotechnology, aimed at optimizing their performance for specific applications.
