Rare earth-doped glass microbarcodes | PNAS

Jan 21, 2003· Rare earth (RE) ions in a silicate glass matrix are an ideal material for the fabrication of encoded beads. REs are a spectroscopically rich species (Fig. 1), a property that facilitates their use as optical codes in a spectral window distinct from fluorescent dyes used for labeling biological samples.

Rare Earth Glass Leica Lenses: A Quick and Quirky Overview

At the time, the only way to achieve glass that provided a very high refractive index and a high Abbe number was to incorporate a "rare earth," thorium oxide or lanthanum oxide, into the glass itself. Both materials emit radiation that can be measured with a Geiger counter, but thorium is significantly more radioactive than lanthanum ...

Why rare earth recycling is rare – and what we can do ...

Apr 07, 2014· LEDs use rare earths, too, but in much smaller amounts than fluorescent bulbs and in ways that make them more difficult to recycle. "I am not convinced that it will be possible to extract rare earths from LEDs in an economical manner," King notes. Despite the challenges, some companies are trying to make rare earth recycling work.

RP Photonics Encyclopedia - rare-earth-doped gain media ...

All rare-earth-doped gain media have in common that the pump and laser transitions are so-called weakly allowed transitions with fairly small oscillator strength. A consequence of this is that the upper-state lifetimes can be long, i.e. of the order of microseconds to milliseconds, so that substantial amounts of energy can be stored in such media. This property makes rare-earth-doped lasers ...

For example, one rarely uses pure silicate glass, but rather some aluminosilicate, germanosilicate, or phosphosilicate glass. Some codopants such as aluminum improve the solubility of rare earth ions and thus allow for higher rare-earth doping concentrations without quenching of the upper-state lifetime.

Color-Change Glass as a Zultanite Imitation | Gems & Gemology

The visible-range absorption spectrum of the loose material (figure 2) showed a typical spectrum of glass with rare earth elements. This spectrum showed bands at 443, 479, 529, and 587 nm. The bands at 443, 479, and 529 nm indicate the presence of Pr 3+, which caused the green or yellowish green color.
