Researchers from Northwest Normal University Discuss Findings in Titanium Dioxide Nanotechnology

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Nanotechnology have been presented. According to news originating from Lanzhou, People's Republic of China, by NewsRx correspondents, research stated, "A facile strategy of cathodic reduction has been developed to successfully prepare Ti3+ self-doped TiO2 nanotube field emitter arrays (TNAs)."

Our news journalists obtained a quote from the research from Northwest Normal University, "This strategy significantly reduces the requirements of instruments and resources compared to the conventional strategies and can controllable introduction of Ti3+ sites (oxygen vacancies) into TNAs with morphology retention. The introduced Ti3+ sites (oxygen vacancies) served as electron donors, can substantially improve the conductivity and decrease the work function of TNAs."

According to the news editors, the research concluded: "Importantly, compared to pristine TNAs, the Ti3+ self-doped TNAs show enhanced field emission (FE) properties including sharply decreased turn-on field from 12.49 to 2.67 V/mu m and large FE current density of 4.31 mA/cm(2) at 4.45 v/mu m."
