Optical properties of bismuth trifluoride thin films.
Films of BiF(3) with thicknesses up to 2.35 microm have been deposited on KCl. Similar optical properties have been obtained in films prepared by thermal evaporation and reactive sputtering in a Freon atmosphere. A very broad transmission range from 2600 A to 20 microm has been measured on BiF(3) films ~1 microm thick. Far ir and Auger spectra are presented. BiF(3) appears promising as a new optical thin film coating for applications not involving high powers at 10.6 microm and longer wavelengths.
