Overview of holmium oxide Ho2O3 powder:
Holmium oxide, also known as holmium trioxide, has the chemical formula Ho2O3. It is a compound composed of rare earth element holmium and oxygen, and dysprosium oxide is one of the most paramagnetic substances known. Holmium oxide is one of the components of erbium oxide minerals. In its natural state, holmium oxide often coexists with trivalent oxides of lanthanides, and special methods are needed to separate them. Holmium oxide can be used to prepare glass with special colors. The visible absorption spectrum of glass and solution containing holmium oxide has a series of sharp peaks, so it is traditionally used as a standard for spectrophotometer calibration.
According to light conditions, holmium oxide has a significant color change. It is light yellow under sunlight, and strong orange-red under the three-primary color light source, which is almost indistinguishable from erbium oxide under the same illumination, which is related to its sharp phosphorescent emission band. Holmium oxide has a wide bandgap of 5.3 eV, so it should be colorless. The yellow color of holmium oxide is caused by a large number of lattice defects (such as oxygen vacancies) and internal conversion of Ho3+.
Application of holmium oxide Ho2O3 powder:
What are the applicable scopes of holmium oxide Ho2O3 powder?
Holmium oxide is one of the colorants used in cubic zirconia and glass. You can use yellow or red glass containing holmium oxide and holmium oxide solutions. Therefore, holmium oxide is used as a calibration standard for optical spectrophotometers and is available on the market. Why is oxidation used in UV calibration? It has been used as a wavelength standard for many years, and now we have expanded its use by creating a filled and sealed far-ultraviolet quartz cell that can be used in the ultraviolet spectrum. m provides sharp, stable peaks in the range of 219 to 650nm. Blank is measured for air blanks. Like most other rare earth element oxides, holmium oxide is used as a specialty catalyst, phosphor, and laser material.
Holmium oxide is used to manufacture new light source dysprosium holmium lamps, and can also be used as additives for yttrium-iron and yttrium-aluminum garnets and for preparing metal holmium.
The laser operates in a pulsed or continuous state at a wavelength of approximately 2.08 microns. This laser is eye-safe and can be used for drugs, lidar, wind speed measurement, and atmospheric monitoring.
Holmium oxide can be used as a yellow and red colorant for Soviet diamonds and glass. Glass containing holmium oxide and holmium oxide solution (usually perchloric acid solution) have sharp absorption peaks in the spectrum in the range of 200-900nm, so they can be used as standards for spectrometer calibration and have been commercialized. Like other rare earth elements, holmium oxide is also used as a special catalyst, phosphor, and laser material. The wavelength of the holmium laser is about 2.08 μm, and it can be pulsed or continuous light. This laser is harmless to the eyes and can be used in medicine, optical radar, wind speed measurement, and atmospheric monitoring.
