Star-shaped VO2 (M) nanoparticle films with high thermochromic performance†
Abstract
Star-shaped VO2 (M) nanoparticles were synthesized by hydrothermal reaction using only ammonium metavanadate and formic acid combined with subsequently mild annealing treatment. Enhanced thermochromic performance was demonstrated upon changing the temperature and the applied pulse voltage for the star-shaped VO2 (M) nanoparticle thin films.
