dc.description.abstract | This research aims to understand the fundamental aspects of annealing on the
electrochromic performance of tungsten oxides, using as-synthesized W18O49 substoichiometric
bundled nanowires benchmarked against commercial WO3 nanoparticles.
Linking detailed structural analyses with the electrochromic measurement results, we have
investigated the electrochromic performance effects of low temperature annealing, up to 350
°C, on tungsten oxide (WOx) thin films, trying to establish the fundamental heat treatmentstructure-performance
loop. We have found that the annealing treatment at low temperature
improved the optical modulation and long-term durability of the WOx thin films, without
changing the structure and morphology of the as-synthesized samples. The 350 °C annealing
was found to have the best stability improvement for the WO3 nanoparticle films during the
electrochromic assessments, with a 4% improvement for Li+
intercalation and a 12%
improvement for de-intercalation, compared with the un-treated WO3 samples. Further
improvements have been achieved for the W18O49 nanowire thin films, with a stability
improvement of 36% for Li+
intercalation and 60% for de-intercalation against the asprepared
W18O49 nanowire samples during the electrochromic performance testing. | en_GB |
