General description

Erbium (III) chloride hexahydrate is a pinkishcrystalline hydrate with unique magnetic and optical properties. It is soluble inwater. It is widely used in the fieldof optical fibers, luminescent devices, and organic synthesis. Its capacity for catalysis is enhanced by the dual Lewis acid and basebehavior.

Application

Erbium(III) chloride hexahydrate can be used:
  • As a chemical vapor deposition(CVD) precursor to fabricate erbium oxide thin films with high dielectric constant.
  • As a dopant to prepare specialty silica optical fibers.
  • As a catalyst for the rapid stereoselective synthesis of trans-4,5-diaminocyclopent-2-enones.
  • To fabricate a hybrid Erbium bis(pentafluorophenyl)phosphinate with long-lived infrared luminescence.
