Upconversion Nanocrystals for Sustainable Technology focuses on the current research directions in upconverting nanocrystals and their role in the development of sustainable technology. Sections focus on the development of low-cost, nontoxic, energy-efficient, upconverting nanocrystals for a wide range of applications. In particular, the book reviews size control synthesis techniques of nanostructured materials in different dimensions, size-dependent properties, and the relationship between material properties and performance. In addition, it discusses the use of upconversion materials for lasers, display, lighting, energy, and biomedical applications--with a focus on the use of these materials to develop more sustainable technologies. This resource is ideally suitable for new entrants in academia and R&D who have a scientific background in materials science and engineering, chemistry, and chemical engineering.
