This book introduces the latest advances made in both fundamental studies and potential
applications of upconversion nanomaterials particularly in the field of high-resolution in
vitro bioanalysis and in vivo imaging. This book starts with the synthesis and characterization
and focuses on applications ranging from materials science to biology. Above all it describes
cutting-edge advances in upconversion nanophosphor (UCNP)-based applications in multiplexed
encoding guest delivery and release systems photodynamic therapy (PDT) solar cells
photocatalysis and so on. The major barriers that currently prevent UCNPs from being used in
mainstream applications are also presented in detail.
