Introduction
This chapter discusses the synthesis of rare earth nanomaterials,
mainly covering rare earth oxides, sulfides, halides, and oxysalts.
Basically, the synthetic routes of rare earth nanomaterials can be
sorted into two main categories: the “dry” methods and the “wet”
methods. The former refers to the synthetic routes like solid-state
reaction, self-propagating synthesis, and several physical routes
(e.g., CVD, PLD, and magnetic sputtering). In contrast, the wet
methods generally involve solution-based processes, during which
various parameters can be finely adjusted (including reaction time,
temperature, concentration, pH value, as well as the utilization
of coordination reagents, templates, mineralizers, etc.), and thus
exhibit particular superiorities in controlling phase purity, chemical
homogeneity, size, and morphology of the final products. In addition,
