Rare Earth knowledge basic

What about the purity of rare earth Fluorides ?

Explain for purity of Rare Earth Fluorideswhat is the purity of Rare Earth FluoridesWhats mean is “TREO”Whats means is the “RE/TREO”? TREO means Total content of Rare Earth Oxide, REO/TREO means this RE element's content in the Total content of Rare Earth Oxide; for example La2O3/TREO: 99.9%, TREO: 99%, means La2O3content is 99.9% in the total content of Rare Earth Oxide and Total content of Rare Earth Fluorides is 99%.

 

Total content of Rare Earth Fluorides are include those elements, Total 16 elements. They are La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc, Y

RE = rare earth

REM = rare-earth Metals

REE = rare-earth elements

REO = rare-earth Oxide

 

About Evaporation material basic knowledge:

Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The other type of vaporization is boiling, which is characterized by bubbles of saturated vapor forming in the liquid phase. Steam produced in a boiler is another example of evaporation occurring in a saturated vapor phase. Evaporation that occurs directly from the solid phase below the melting point, as commonly observed with ice at or below freezing or moth crystals (napthalene or paradichlorobenzine), is called sublimation.

 

Application for Film deposition, Thin films may be deposited by evaporating a substance and condensing it onto a substrate, or by dissolving the substance in a solvent, spreading the resulting solution thinly over a substrate, and evaporating the solvent.

The rate of evaporation depends on the material and such factors as the temperature, the surface area, amount of ventilation, and the pressure exerted on the surface

 

Thermal vacuum deposition is one method for fabricating thin films under a high vacuum environment also addressed as "thermal evaporation method". With this method, an electron beam (e-beam) or resistive heating is usually used to evaporate the desired material inside the vacuum coating chamber, which then adheres to a substrate placed above it. This method can classified as a form of PVD, which stands for physical vapor deposition, and is suitable for fabricating high-quality thin films with thicknesses on the order of nanometers on glass, plastic, films, metals, and almost any other kind of material. An e-beam can be used to melt evaporation material with melting points even above 2000 degree, which are common for thin films on optical components, some of which consist of more than 300 layers.

 

Some of the characteristics of a good optical thin film are as follows: good transmittance, low absorption, stable refractive index, high packing density, low scattering, low stress, reasonable hardness, good adhesion, chemical stability, environmental resistance. Among the several parameters that influence thin film quality, the choice of evaporation material is critically important.

 

Wide application as a thin film material:

Our evaporation material can be used to manufacture the following:

optical thin film coatings such as AR coatings, HR coatings, and coatings for most optical filters

functional thin film coatings such as transparent conductive coatings

protective overcoatings

coatings for gas barrier applications

antiwear films

heat-resistant coatings

colored decorative coatings

optical thin film coatings

coatings for laser optics applications
