An Investigation of the Optical-and-Thermophysical Characteristics of Condensed Media of Polymer Series under Conditions of High Vacuum

摘要

A brief description is made of the optical-diagnostic module and of the experimental procedure of investigation of the optical characteristics of condensed media in the short-wave spectral range (the range of quantum energies of probing synchrotron radiation hv ～3.5-25 eV under conditions of high vacuum), and results are given of an experimental investigation of spectral reflectance and absorptance, excitation spectra, and quantum yield of luminescence of readily ablating dielectrics based on elements of the polymer series. Use is made of the Kurchatov source of synchrotron radiation at pre-threshold (for developed surface evaporation) values of power density of probing radiation I_0 ～ 10~(12) photon/(cm~2 s) and at surface temperature of condensed targets T ～ 300-77 K.
