Description:

Holmium oxide has some pretty dramatic color changes depending on the lighting conditions. In daylight it is a tannin color. Under trichromatic light, it's a fiery orange-red that is barely distinguishable from the way erbium oxide looks under the same lighting. This is related to the sharp emission bands of the phosphors.

Areas of application:

  • Holmium oxide is one of the colorants for zirconia and glass and provides a yellow or red color. Glass containing holmium oxide and holmium oxide solutions (usually in perchloric acid) has sharp optical absorption peaks in the spectral range from 200 to 900 nm. They are therefore used as calibration standards for optical spectrophotometers and are commercially available. Like most other oxides of rare earth elements, holmium oxide is used as a specialty catalyst, phosphor, and laser material. The holmium laser operates at a wavelength of around 2.08 micrometers, either in the pulsed or in the continuous range. This laser is eye-safe and is used in medicine, lidars, wind speed measurements and monitoring the atmosphere.
