CAS 12020-65-4 Europium Sulphide EuS use as laser window materials

Brief Description Of  Europium Sulphide EuS

Europium (II) sulfide is the inorganic compound   with the chemical formulaEuS.

It is a black, air-stable powder. 

Its Curie temperature (Tc) is 16.6 K. Below this temperature EuS behaves like a ferromagnetic compound, and above it exhibits simpleparamagntic  properties.

EuS is stable up to 500 °C in air, when it begins to show signs of oxidation. 

In an inert environment it decomposes at 1470 °C.

Structure of  Europium Sulphide EuS

EuS crystallizes in face-centered cubic  (FCC) crystal lattice with the rock salt structure.

Both europium and sulfur have octahedral coordination geometry  with a coordination number  of six.

The Eu-S bond lengths are 2.41 Å.

Application of Europium Sulphide EuS

In the past few decades, a new interest has been exhibited in the synthesis of EuS, as well as its oxygen  analog EuO, because of their potential use as laser window materials, insulating ferromagnets, ferromagnetic semiconductors, and magnetoresistant, optomagnetic, and luminescent materials.
