| Summary |
Upconversion Nanophosphors provides detailed information about various lanthanide-based upconversion nanoparticles and their application in different fields. It will also help solve fundamental and applied problems of inorganic phosphor materials showing upconversion behavior, as well as generate innovative ideas related to the application of inorganic phosphor materials. This book will prove to be an invaluable reference work for scientists, engineers, industrial experts, and masters and PhD students working in the field of upconversion and materials science. |
