title: Plasma-electrolysis synthesis of TiO2 nano/microspheres with optical absorption extended into the infra-red region.
abstract: A novel plasma-electrolysis method is introduced to synthesize high-quality TiO(2) nano/microspheres that exhibited excellent optical absorption covering the range from ultraviolet to infra-red. Both experimental and theoretical results show that the oxygen vacancies in the TiO(2) spheres are primarily responsible for this wide absorption.
