About Europium Nitride EuN Powder:

Europium nitride is a semiconductor that contains non-magnetic Eu3+, but substoichiometric europium nitride contains a mixture of Eu in the 2+ and 3+ charge states. The results show that when the concentration of Eu2+ is close to 15% ~ 20%, the silver is ferromagnetic, and the Curie temperature is up to 120 K. The polarization of Eu3+ follows that of Eu2+, which demonstrates the intrinsic ferromagnetism of EUN and, therefore, is a new type of diluted magnetic semiconductor. Transport measurements revealed possible exchange mechanisms.

Europium nitride is a semiconductor that contains a non-magnetic 3+, but substoichiometric europium nitride contains a mixed charge state of 2+ and 3+. We show that at \2+ ~ concentrations around 15-20%, silver is ferromagnetic and Curie temperatures up to 120 K. The polarization of 3+ ~ is the same as that of 2+, which confirms the inherent ferromagnetism of the silver atom. Therefore, the silver atom is a new type of diluted magnetic semiconductor. Transport measurements revealed possible exchange mechanisms.

The stability and chemical properties of EUN powder are active. EUN will produce hydrogen oxide by oxidative hydrolysis in the air, release ammonia in the effluent, and dissolve in dilute acid.

Applications of Europium Nitride EuN Powder :

Electronic field

In the field of electronics, europium nitride is widely used in the manufacture of high-brightness, high-efficiency LED devices. This is because europium nitride has the characteristics of high brightness and high efficiency, making it one of the ideal materials for manufacturing high-brightness LED devices. In addition, europium nitride can also be used to manufacture superconducting materials and electrode materials for electronic devices.

Optical field

In the field of optics, europium nitride has excellent luminous properties and optical stability and is widely used in the manufacture of lasers, amplifiers, and other optical devices. Because of its wide emission spectral range and high luminous efficiency, it has become one of the important materials for manufacturing efficient optical devices. In addition, europium nitride can be used in the manufacture of optical fibers and other optical communication devices.

The field of catalysis

In the field of catalysis, europium nitride has excellent catalytic activity and stability and is widely used in various catalytic reactions. For example, europium nitride can be used as a catalyst in the production of ammonia, syngas, and other chemicals. In addition, europium nitride can also be used in automobile exhaust treatment, fuel cells, and other environmental protection fields.

Magnetic materials field

In the field of magnetic materials, europium nitride, as a magnetic material with high permeability and low loss characteristics, is widely used in the manufacture of high-frequency magnetic devices and electronic storage devices. For example, europium nitride can be used in memory devices such as high-density hard drives and memory chips.

Production Method of Europium Nitride EuN Powder :

Direct nitriding

Direct nitriding is a common method for producing europium nitride. The method is to mix europium salt (such as europium nitrate) with ammonia and carry out a direct nitriding reaction at a certain temperature to produce europium nitride. The reaction equation is as follows:

Eu(NO3)3 + 6NH3 + 5H2O = EuN + 15H2O

The advantage of the direct nitriding method is a simple process and easy operation, but the disadvantage is that ammonia is volatile, resulting in an unstable reaction process. In addition, this method requires the use of a large amount of ammonia, and the cost is high.

Second, reduction nitriding method

Reductive nitriding is a method of reducing europium oxide to europium nitride at high temperatures. The method is to mix europium oxide (such as europium oxide) with a metal hydride (such as sodium borohydride) and undergo a reduction reaction at high temperatures to produce europium nitride. The reaction equation is as follows:

Eu2O3 + 2NaBH4 + 2NH3 = 2EuN + 2NaBO2 + 6H2

The reduction nitriding method has the advantages of low reaction temperature and simple operation. However, this method requires the use of high-purity raw materials, higher requirements for equipment, and higher costs.

Third, plasma nitriding method

Plasma nitriding is a method of producing europium nitride at low temperatures using plasma technology. The method is to place europium salt or europium oxide in a plasma reactor, pass nitrogen plasma, and nitride reaction at low temperature to produce europium nitride. The advantages of this method are high speed and low requirements for equipment. However, this method requires the use of high-purity raw materials and complex equipment, and the cost is high.

Chemical vapor deposition method

Chemical vapor deposition is a method for preparing europium nitride. The method is to mix europium salt or europium oxide with a gas such as nitrogen and undergo a chemical reaction at a certain temperature to produce europium nitride. The advantages of this method are that the prepared europium nitride has high purity and fine particles, which is suitable for the preparation of high-performance materials. However, this method requires the use of high-purity raw materials and complex equipment, and the cost is high.
