SOME OPTICAL PROPERTIES OF SEVERAL EVAPORATED RARE EARTH METALS

Abstract

Rare earth metals of Er, Yb, Ho, Tb, Gd, and Tm were evaporated on quartz and glass substrates as optical film surfaces. Vacuum evaporation techniques and the possible use of these metals as technical ''getters'' is discussed. The optical properties of subject rare earth metals are presented, as well as data on visible and infrared reflectance. Values of refractive index and extinction coefficient are given for two wavelength values, 0.54 and 0.60 microns. Films of Er and Yb showed high reflectance in the infrared and good atmospheric stability. (Author)
