High-Purity Europium Oxide Neutron Absorber Cores - China Suppliers & Factory for Advanced Optoelectronics
Trivalent europium ions (Eu³⁺) serve as an outstanding red luminescent center. Under ultraviolet or electron beam excitation, they can emit red fluorescence with exceptionally high color purity and brightness, a characteristic that is irreplaceable.
By modifying the matrix material or introducing divalent europium ions (Eu²⁺), it is possible to control the luminescent behavior, achieving fluorescence that ranges from blue to green, offering high flexibility.
The fluorescence performance remains stable in high-temperature and radiation environments, ensuring a long lifespan.
Europium oxide has a high thermal neutron absorption cross-section (~5,800 barns), making it suitable for neutron shielding and control.
After absorbing neutrons, it generates isotopes with specific radioactivity. This characteristic can be used for radiotracing, but it also means that caution must be exercised in handling the radioactive issues that arise from its activation in nuclear applications.
The melting point exceeds 2350°C, which can meet the basic requirements of high-temperature application environments.
It exhibits excellent corrosion resistance in various chemical environments and molten metals.
Trivalent europium ions (Eu³⁺) act as a red luminescent center. When excited by ultraviolet light or electron beams, they emit highly pure and bright red fluorescence.
Yes, the emission color is highly flexible. By changing the matrix material or introducing divalent europium ions (Eu²⁺), the fluorescence can be tuned to range from blue to green.
Europium exhibits high stability, maintaining its fluorescence performance reliably even when subjected to high-temperature and radiation environments.
Europium oxide features a high thermal neutron absorption cross-section of approximately 5,800 barns, making it exceptionally effective for neutron shielding and control applications.
Yes. When Europium absorbs neutrons, it becomes activated and generates radioactive isotopes. While useful for radiotracing, careful handling is required to manage the resulting radioactivity.
It has a melting point exceeding 2350°C and demonstrates strong chemical inertness, providing excellent corrosion resistance in various chemical environments and molten metals.
