Scandium Oxide, Sc2O3 for Optical Coating


Scandium oxide, Sc2O3, produces high-index film layers that are transparent to wavelengths as short as 225 nm in the UV region. The films are insoluble and hard.

Film Properties of Scandium Oxide Sc2O3

Scandium oxide films require an electron-beam source to reach evaporation temperature. Amorphous films can be deposited below 150° C substrate temperature.


Physical Properties of Solid Material Scandium Oxide Sc2O3


Evaporation Parameters of Scandium Oxide Sc2O3


Evaporation Procedure of Scandium Oxide Sc2O3

Keep the material in a dry atmosphere, preferably heated to reduce moisture adsorption. Precondition with a low power sweep until spitting and outgassing subside as a rate of 1Å/sec is approached (~15 min). Evaporation is by sublimation. Continue sweeping to prevent burrowing.

Applications of Scandium Oxide Sc2O3

The high index value, transparency, and layer hardness make scandium oxide suitable for the high index component of UV, AR and bandpass coatings. High damage thresholds have been reported for combinations with silicon dioxide or magnesium fluoride for use in AR, beamsplitters, and bandpass filter coatings at 248 nm and 351 nm.
