Abstract: In 2000, we published the first paper on the nanoscale upconversion properties of erbium (Er3+)-doped nanocrystals. Over the course of the last 15 years, the field of rare earth doped upconverting nanoparticles has exploded, progressing from the basic understanding of the photophysical properties governing their nanoscale upconversion to their use in a plethora of applications, with considerable focus in biology and medicine. Here, we present the study of various optically-excited (and emitting) core/shell rare earth nanostructures and demonstrate how their various emissions spanning the UV-visible-NIR regions could be harnessed for applications such as cell-labeling, bioimaging, and nanothermometry. We will also discuss hybrid core/shell nanostructures (Figure below) that have the ability to deliver several modalities in a single, optical nanoplatform.
