Description

Yttrium Oxide Europium-Doped is a high-purity inorganic phosphor material where trivalent europium ions (Eu³⁺) are incorporated into a yttrium oxide (Y₂O₃) host lattice. This compound is critically important for its exceptional red luminescent properties when excited by ultraviolet, electron beam, or X-ray radiation. It is an essential raw material for manufacturers in the display technology, lighting, and security printing industries, enabling vibrant color and high efficiency in advanced applications.

Application

• Phosphors for CRT & FED Displays: As the dominant red-emitting component in cathode ray tubes (CRTs) and field emission displays (FEDs).
• Plasma Display Panel (PDP) Phosphors: Used in the red phosphor layers of plasma television and monitor screens.
• Fluorescent Lamp Phosphors: Employed in trichromatic fluorescent lamps to produce high-quality white light with excellent color rendering.
• X-Ray Intensifying Screens: Acts as a red-emitting phosphor in medical and industrial X-ray imaging systems to convert X-rays into visible light.
• Security Inks & Anti-Counterfeiting: Utilized in specialized inks for banknotes, certificates, and branded products due to its stable and specific luminescence under UV light.
• LED Phosphors: For wavelength conversion in certain LED configurations to achieve specific red spectral outputs.
• Scintillation Detectors: Potential use in radiation detection and measurement equipment.

Quality Control

Our Yttrium Oxide Europium-Doped is produced under stringent quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as europium doping concentration, particle size distribution, phase purity, and luminescent intensity are rigorously tested. Certificates of Analysis (COA) detailing these specifications are provided with each shipment. Production can adhere to relevant industry standards based on customer requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C/59-77°F) with low humidity. For long-term storage, consider the use of a desiccated environment or inert gas blanket to prevent moisture absorption and maintain optimal phosphor performance.
