The synthesis of rare earth fluoride based nanoparticles

Abstract

The requirement for narrow emission profiles and systems that do not include metals perceived to be cytotoxic, has led to an increase in the reports on rare-earth (Ln) materials, with fluoride-based materials in particular attracting attention. This class of compounds includes rare-earth fluorides (LnF(3)), rare-earth oxyfluorides (LnOF) and alkali metal rare-earth fluorides (MLnF(4), where M represents an alkali metal). Here we will describe the main reactions outlining key developments in roughly chronological order.

Metal–Organic Derivatives with Fluorinated Ligands as Precursors for Inorganic Nanomaterials

“…508 Single-crystalline and monodisperse LaF 3 triangular nanoplates in trigonal structure were synthesized via thermolysis of [La(TFA) 3 (H 2 O) x ] in a hot oleic acid/1-octadecene solution. 509 The high uniformity of these nanoplates allowed the formation of nanoarrays arranged with long-range translational and orientational order in several microns.…”

Lanthanide‐Doped Nanocrystals: Strategies for Improving the Efficiency of Upconversion Emission and Their Physical Understanding

“…[1, 15,[44][45][46] However, the majority of them focused on the synthesis and biological applications of upconverted materials. [15,[47][48][49] Haase and Schäfer [50] illustrated the current state of lanthanide-doped upconverted nanoparticles and mainly focused on synthesis, surface functionalization, and potential applications.…”

Polyol-mediated solvothermal synthesis and luminescence properties of CeF3, and CeF3:Tb3+ nanocrystals

“…Compared with the conventional oxide-based systems, RE fluorides possess advantageous properties as fluorescent host materials such as low vibrational energies, and the subsequent minimization of the quenching of the excited state of the RE ion [15,16]. Furthermore, they exhibit high ionicity, electron-acceptor behavior, high resistivity as well as adequate thermal and environmental stability and therefore are considered as ideal host materials for luminescent RE ions.…”
