Optical properties of bismuth trifluoride thin films
Abstract:
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.
