Paper Abstract

The optical absorption in thin films of electrochromic oxides of tungsten and molybdenum has over the solar spectral range at temperatures from about 100 K to 365 K. The films were depos at room temperature by RF plasma enhanced chemical vapor deposition and then converted to th injection compounds LixWO3 and LixMoO3 by reaction with n-butyl lithium in a water-free an environment to duplicate their colored elctrochromic state. The optical absorption in the LixW03 films consists of a broad peak centered near 1.7 eV. The Absorption in the LixMo03 films consists of a broad band centered near 1.3 eV, a temperature dependent Urbach band edge near 3 eV plus a very broad tailing absorption connecting these two features. The optical absorption in these materials in interpreted in terms of a small polaron absorption process and temperature dependent structual disorder.
