A rare earth, preferably lanthanum or neodymium, is selected for the A-site doping.

As rare earth, the lamp uses Dy alone.

As rare earth, the fill in each case uses Tm alone.

The rare-earth-oxide-containing powder intended for being mixed with the base powder of UO2 can also be produced advantageously by common precipitation from a solution, in which uranium and the rare earth are dissolved.

The last-mentioned fifth coupler 24 receives pump light from the pump-light source 2 via a second output branch 26 of the first coupler 3, and a second input branch 27 of the fifth coupler 24, which is connected to the output branch 26, where the light propagates together with the signal light from the subscriber through the output branch 28 of the fifth coupler 24, and through an input 29 into a second waveguide 30, which is also doped with a rare earth element, such as erbium e.g., and is called the second active waveguide 30 in the following.

An output branch 11 of the second coupler 6 is connected to a first branch 13 of a third coupler 12, whose opposite branch end 14 is connected to the input 15 of a first waveguide 16, which is doped with a rare earth element, such as erbium e.g., and is called the first active waveguide in the following.

In a method as defined in claim 9, wherein said oxidizable additive has cations selected from the group consisting of indium, antimony, cadmium and rare earth metals having a valence of +3 or +5.

The rare-earth-oxide-containing powder intended for being mixed with the base powder of UO2 can also be produced advantageously by common precipitation from a solution, in which uranium and the rare earth are dissolved.

The truffle, aprecious and rare fruit of the earth, is celebrated in many Italian cities at different times of the year.

With an inventive base element with inventive production in the working range from 100° C. to 150° C. it is advantageously possible to utilize the magnetic properties of the magnetically active material, in particular a rare earth element.

For the semiconductor light source according to the present exemplary embodiment, and for the other embodiments of the semiconductor light source, orthosilicate luminescent materials such as those of general formula M 2 SiO 4:SE—where M represents for example an alkaline earth metal such as Mg, Ca, Sr or Ba, and SE represents a rare earth such as europium (Eu 2+)—are particularly suitable.

In a further exemplary embodiment of an inventive electric machine, the magnetically active material does not contain a chemical element, in particular a rare earth element, in the concentration required to reduce the deterioration of the highly coercive properties of the magnetically active material during a sinter process.

The "mother" of these HTS is a cuprate containing the rare earth lanthanum, the so-called lanthanum cuprate.

Rare earth containing bastnasite has been mined since 1912 and previous exploration has identified widespread bastnasite mineralisation with average grades in the order of 3.6% TREO (Total Rare Earth Oxides).

This is the first time ever that rare earths have been found to have such a biological function.”

The description also refers, by way of example, to a support based on a refractory oxide within the meaning of Claim 1, which already includes - that is, independently of the active phase - cerium oxide (one such trivalent rare earth) together with alumina (page 2, lines 44 to 47).

For example, the nitride luminescent material system is a nitridosilicate such as M 2 Si 5 N 8:Eu 2+ with an alkaline earth metal M such as Ba, Ca or Sr. As an alternative or in addition, it is possible to use an aluminium silicon nitride luminescent material which is doped with a rare earth material, such as MAlSiN 3:SE, where M in particular represents an alkaline earth metal such as Ba, Sr or Ca, and SE represents a rare earth.

Essentially, consolidate and control the rare earth market.
