Abstract
Niobium oxide electrochromic thin films were prepared by reactive DC magnetron sputtering method. Electrochromic properties of prepared films strongly depended on the substrate temperature during sputtering. The sample with a substrate temperature of 500° C was well crystallized and showed excellent electrochromism. Its integrated luminous transmittance could be controlled from 26% to 89%. Optical modulation range was small for samples with low substrate temperature and these samples showed fast degradation.Keywords
