Abstract
The properties of phosphor materials in nanoscale form, usually termed “nanophosphors”, present particular aspects that are worthy of extensive investigations at both fundamental and applicative level. Nanophosphors are mainly represented by compounds doped with rare earths, whose 4f optically active electrons are protected from static and dynamic perturbations by the 5s and 5p subshells.
In this paper we first review the spectroscopy of rare earth ions and the properties of bulk phosphors (physical mechanisms underlying luminescence processes, thermal line broadening and line shift) and then consider the corresponding scenario at the nanoscale and discuss the role that spectroscopy may play in the investigation of nanophosphors. The paper aims at giving a background to a reader new to the spectroscopy of nanophosphors and useful points of discussion as well as guidelines for further studies.
