Phosphor - Wikipedia

The development of color TV took a long time due to the search for a red phosphor. The first red emitting rare-earth phosphor, YVO 4:Eu 3+, was introduced by Levine and Palilla as a primary color in television in 1964. In single crystal form, it was used as an excellent polarizer and laser material.

Prediction of the quantized axis of rare-earth ions: the ...

An electrostatic model based on the effective-point-charge approach is proposed to predict the quantized axis of rare-earth ions, even in low symmetry. The effective charges of coordination atoms create an electrostatic potential interacting with the aspherical 4f electron cloud of the rare-earth ion.

How Is The Strength Of A Magnet Measured | First4magnets

HOW IS THE STRENGTH OF A MAGNET MEASURED? When we consider the 'strength' of a magnet, there are several measurements that all contribute to a magnet's strength in different ways, which can often seem confusing. It also depends on what is meant by strength; pulling force and magnetic field strength are often both summarised as strength.

Anisotropy of rare-earth magnets — Research Nebraska

Rare-earth intermetallics such as Nd 2 Fe 14 B and Sm-Co are widely used as high-performance permanent magnets, because they combine high magnetocrystalline anisotropy with reasonable magnetization and Curie temperature. The anisotropy is a combined effect of spin-orbit coupling and electrostatic crystal-field interactions. The main contribution comes from the rare-earth 4f electrons, .

It is shown that a model with three layers of charges reproduces the electrostatic field generated by the ligands and that the covalency plays a qualitative role. The one‐electron character of crystal field theory is discussed and shown to be valuable, although it is not completely quantitative.

A Review of the Global Supply of Rare Earths - rsc

China's dominance of the rare earths market was not a concern to the ROW until the mid-late 2000s, as rare earth export quotas tightened and there was little ROW production to fall back on By 2005, China accounted for 96% of global rare earth production, including 99.8% of HREO production
