Rare earths in glass technology - ScienceDirect

The rare-earth oxides develop a stabilizing action on the original colour and allow at the same time a high transparency to be main- tained also under the most severe radiation. There- fore, a wide use of such special glasses for TV- colour tubes and windows for the nuclear industry has been made.

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 ...

Rare Earth Elements: Where in the World Are They?

Other important uses of rare earth elements are in the production of special metal alloys, glass, and high-performance electronics. Alloys of neodymium (Nd) and samarium (Sm) can be used to create strong magnets that withstand high temperatures, making them ideal for a wide variety of mission critical electronics and defense applications.

Rare-earth-doped transparent glass ceramics

Glass ceramics such as Zerodur® – an aluminosilicate glass with 50-nm β-quartz crystals and with 70% of crystalline phase – has almost zero thermal expansion (0 ± 0.02 × 10 –6 K –1) in the temperature range of 0–100 °C and ∼ 90% transmittance between 0.6 and 2.0 μm …

ACTION OF GAMMA RADIATION ON ALUMINOCALCIUM GLASSES ACTIVATED BY RARE ...

Porous glass was impregnated with rare-earth and transition-metal ions and consequently sintered at 1100 deg. C into a compact nonporous glass. Reduction sintering is indispensable for obtaining fluorescence glass with high emission yield. Sintering of glass impregnated with Eu ions in a reducing atmosphere enhances the emission intensity by ...

Using Rare Earth Oxides to Make Fluorescent Glasses

Rare Earth Elements in Glass Production. In the field of glass production, rare earth oxides have long been studied. More specifically, how the properties of the glass may change with the addition of these compounds. A …

rare earth glass_"rare earth glass"

rare earth glass: 1. After a year of further development, the rare earth glasses were introduced to great acclaim at the Spring 1929 trade show in Leipzig. 2. The Alexandrit and Heliolit names were registered as trademarks in June 1929 . The earlier date of 1925 sometimes given for rare earth glass refers to an award for glass design, not glass composition. …

Rare earth doped glass–ceramics containing NaLaF4 nanocrystals

Rare earth activated glasses and glass–ceramics can be used as scintillators for high-energy physics, X-ray computed tomography and radiation monitoring . Ceramic and glass scintillators can be made in various shapes and sizes if correctly cooled after glass casting. Cost advantages over single crystals appear when large detectors are necessary.

RARE EARTH RADIOACTIVE GLASS LENSES MADE BY LEITZ/LEICA

A total of only 550 bodies were ever made so any Leica KE-7A is a rare indeed. The standard KE-7A outfit included the rare 50mm f/2 Elcan (which stands for E. Leitz, Canada) lens, a unique formula consisting of 4 non-cemented, air-spaced elements designed to withstand the rigors of extreme weather and service in active combat zones.

Using Rare Earth Oxides to Make Fluorescent Glasses - AZoM.com

Rare Earth Elements in Glass Production. In the field of glass production, rare earth oxides have long been studied. More specifically, how the properties of the glass may change with the addition of these compounds. A German scientist named Drossbach began this work in the 1800s when he patented and manufactured a mixture of rare earth oxides ...

Rare-earth-doped transparent glass ceramics - ScienceDirect

The presence of residual OH species in the glass host increases the non-radiative decay rates, because of coupling between the RE states and the high energy stretching vibrations of the OH groups (∼3200 cm –1).This contribution to non-radiative decay is very important in the case of the Er 3+ ion, since two OH phonons are sufficient to bridge the energy gap between …

Rare earth-doped glass microbarcodes | PNAS

Rare earth (RE) ions in a silicate glass matrix are an ideal material for the fabrication of encoded beads. REs are a spectroscopically rich ( 8) 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.
