Erbium Oxide: A Deep Dive into its Properties

Erbium oxide is a pink to red crystalline powder that exhibits strong absorption bands around 1500 nm. This wavelength region coincides with the low-loss window of silica optical fibers, making erbium oxide an excellent candidate for amplifying optical signals transmitted through these fibers.

Furthermore, erbium oxide possesses long fluorescence lifetimes, allowing for efficient energy storage and emission. When excited by a pump laser, Er3+ ions within the oxide lattice absorb energy and transition to higher energy levels. These excited ions then decay back to their ground state, emitting photons with wavelengths around 1550 nm – precisely where optical signals travel efficiently in silica fibers.

Here’s a table summarizing some key properties of erbium oxide:
