Quantifying and controlling the magnetic dipole contribution to1.5−μmlight emission in erbium-doped yttrium oxide

Surface-Directed Synthesis of Erbium-Doped Yttrium Oxide Nanoparticles within Organosilane Zeptoliter Containers

We introduce an approach to synthesize rare earth oxide nanoparticles using high temperature without aggregation of the nanoparticles. The dispersity of the nanoparticles is controlled at the nanoscale by using small organosilane molds as reaction containers. Zeptoliter reaction vessels prepared from organosilane self-assembled monolayers (SAMs) were used for the surface-directed synthesis of r...

Erbium - ytterbium - yttrium compounds for light emission at 1

Silicon microphotonics has emerged as the leading technology to overcome the interconnect bottleneck that limits a further increase of computation power following Moore's law. Optical interconnects between different electronic microprocessors in an electronic-photonic integrated circuit (EPIC) can provide a fast, low-loss and highbandwidth alternative to electrical interconnects, which suffer f...

Exciton–erbium coupling and the excitation dynamics of Er3+ in erbium- doped silicon-rich silicon oxide

Effect of metallic surface on electric dipole and magnetic dipole emission transitions in Eu3+ doped polymeric film.

Spontaneous emission of Eu(3+) ions is studied in thin organic films deposited onto several different substrates. It has been demonstrated that the presence of a metallic surface in close vicinity to emitting Eu(3+) ions causes modifications of their spontaneous emission spectra, in particular, the change in the relative strengths of magnetic-dipole and electric-dipole transitions. The characte...

Preparation and photoluminescence of yttrium hydroxide and yttrium oxide doped with europium nanowires

Single-crystalline Y(OH)3:Eu nanowires have been prepared by polymer-assisted hydrothermal method. The yields of the nanowires were higher than 95%. XRD patterns showed that the products were the hexagonal Y(OH)3 structure. SEM images displayed that the nanowires consisted of nanobelts and nanorods. The nanorods have the diameter of about 85 nm and length up to several tens of microns, and the ...
