Synthesis of gold nanorod/neodymium oxide yolk/shell composite with plasmon-enhanced near-infrared luminescence

Abstract

AuNR@Nd2O3 yolk/shell nanocomposites are synthesized by a hydrothermal method; the luminescence of Nd3+ is enhanced 4.6 times by AuNRs.

Switching to the brighter lane: pathways to boost the absorption of lanthanide-doped nanoparticles

“…A strategy complementary to the one discussed above is the growth of a Ln 3+ -containing shell on a PNP. Different approaches have been explored, such as growth of the Ln 3+ -doped shell directly on the surface of the plasmonic particle, 63 use of a spacer between the two species, 33,[64][65][66] as well as selective etching of the silica spacer to achieve rattle-like structures 65,67 . Stucky and co-workers grew a Y2O3:Er 3+ shell on SiO2-coated silver NPs 65 adapting a strategy for the preparation of rare-earth nanostructures with urea and rare-earth salts.…”

“…Lastly, moving from UC, the enhancement of Nd 3+ downshifting emission was achieved in GNR/Nd2O3 nanocomposites. 67 The structure was prepared via a hydrothermal method at relatively low temperature (85 °C) and tuning of the LSPR allowed reaching a maximum enhancement factor of approximately 4.6 for Nd 3+ emission at 873 nm under 730-nm excitation.…”

Nonconventional magnetic phenomena in neodymium thin film

“…Besides the practical applications, the Nd element is an integral component in the numerous scientific investigations of fundamental importance in solid state and materials physics. For instance, Nd-based compounds are at the forefront of the study of quantum magnetism or the exploration of plasmonic properties [10][11][12][13][14][15]. More recently, an emergent nanomaterial with a honeycomb motif, created using the Nd element, was used to demonstrate a highly novel state of the Wigner crystal of magnetic charges [16].…”
