Quantum Dots Nanocamera for Molecules and Today's Challenges

Quantum dots have been at the center of many early developments in what is now commonly called nanoscience and nanotechnology. Quantum dots are tiny specs of semiconductor matter that are a few nanometers across. The focus of the nanotech team¿s research has been on particles fabricated via colloidal chemistry, known as colloidal or nanocrystal quantum dots. ¿Because of their size-controlled electronic properties and chemical flexibility, quantum dots can be viewed as ¿artificial atoms¿ that can be engineered on demand to address a specific physical problem or a need of a certain application,¿ Klimov said.Over nearly two decades, quantum dot scientists have driven the evolution of colloidal quantum dots from a subject of laboratory curiosity to a versatile class of materials exploited in a wide range of emerging technologies such as e-book readers and television sets.in this book we study QD properties and applications in meany fields in our life. The writing of this book has been very simple to make it easy to understand for non-specialized readers
