About Erbium oxide

The pink-rose powder that makes erbium oxide (Er2O3, CAS 12061-16-4, molecular weight 382.52 g/mol) visually distinctive is a direct consequence of the same 4f electron transitions that make it indispensable in fiber optic telecommunications. US-based erbium oxide manufacturers and suppliers serve the photonics, medica...

Optical Fibers

Dopant in Erbium-Doped Fiber Amplifiers (EDFAs) for telecommunications

Glass & Ceramics

Provides a pink tint to glass and is used in nuclear control rods as a burnable neutron poison

Synthesis Upconversion

Essential in the synthesis of phosphors for biomedical imaging and anti-counterfeiting

Detail 1

Store in a dry area at ambient temperature

Detail 2

Keep in original moisture-proof packaging. Rare earth oxides can slowly absorb moisture and CO2 from the atmosphere if left exposed

Detail 3

Non-flammable, but standard protective gloves and safety glasses are recommended to prevent mechanical irritation from the powder on storage
