Nano Erbium Oxide Er₂O₃ 99.99% High Purity Powder for Fiber Amplifiers & Upconversion

Nanometer erbium oxide is a pink to light pink powder. It has a high melting point of approximately 2340°C and a density of about 6.64 g/cm³. This rare earth oxide is paramagnetic at room temperature and insoluble in water, though it dissolves in strong inorganic acids. Its crystal structure is cubic (C-type). A key property is its upconversion luminescence, where it absorbs low-energy photons (e.g., infrared light) and emits higher-energy photons (e.g., visible light). Due to the high surface activity of the nanoparticles, storage sealed in a dry, oxygen-free environment is recommended to prevent oxidation and agglomeration.

Application Fields

1. Optical Fiber Communication: Serves as the core gain medium in Erbium-Doped Fiber Amplifiers (EDFAs), crucial for amplifying the 1550 nm light signals in long-distance communication networks.
2. Medical Diagnostics: Utilized as a biological fluorescence label in high-sensitivity, low-background bioassays and imaging, leveraging its upconversion properties for applications like early cancer detection.
3. Upconversion Luminescence: Used in security inks and anti-counterfeiting materials that emit visible light under IR illumination. Also explored as an additive to enhance infrared light absorption in silicon solar cells.
4. Nuclear Industry: Its high neutron absorption cross-section makes it suitable for use in control rods in nuclear reactors.
5. Specialty Glass & Ceramics: Acts as a coloring agent, imparting a distinctive pink hue, and as an additive to improve sintering and mechanical strength in ceramics.
