Description

Calcium Sulfide (Cas), Cerium-Doped is a specialized inorganic phosphor material where cerium ions are incorporated into the calcium sulfide host lattice. This doping process is critical for imparting specific luminescent properties, making the material valuable for advanced optoelectronic applications. It is primarily sought by manufacturers and R&D teams in the electronics, display technology, and specialty pigment industries for its ability to emit light under specific excitation conditions.

Application

• Phosphor in Electroluminescent (EL) Displays: Used as a key component in thin-film electroluminescent (TFEL) panels and devices.
• Luminescent Pigments and Paints: Employed in the formulation of specialty safety signs, glow-in-the-dark coatings, and artistic pigments.
• Optical Sensor Materials: Serves as a sensing layer in devices that detect specific types of radiation or light.
• Research & Development: Utilized in academic and industrial labs for developing new photonic materials and studying energy transfer processes.
• Light-Emitting Diodes (LEDs): Potential use in wavelength conversion layers for next-generation LED architectures.
• Radiation Dosimetry: Investigated for use in materials that measure exposure to ionizing radiation.

Quality Control

Our Calcium Sulfide (Cas), Cerium-Doped is produced under controlled conditions to ensure batch-to-batch consistency and performance. Quality is verified through a suite of analytical techniques to confirm chemical identity, doping concentration, phase purity, and luminescent efficiency. A Certificate of Analysis (COA) detailing specific lot results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place, ideally under an inert atmosphere such as argon or nitrogen to prevent degradation. Recommended storage temperature is 15-25°C.
