General description

Holmium (III) perchlorate is a yellow solution widely used to verify the wavelength scale of UV/visible spectrophotometers with sharp absorption peaks at 200-900 nm.

Application

Holmium(III) perchlorate solution can be used:
  • As a precursor to synthesize Holmium(III) complex nanoparticles.
  • To study the stability of holmium oxide for the establishment of wavelength standards for spectrophotometer.
