A novel plasma-electrolysis method is introduced to synthesize high-quality TiO₂ 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 TiO₂ spheres are primarily responsible for this wide absorption.
