To sanitize and disinfect areas from bacteria and viruses requires UV radiation sources that emit sufficiently high doses of UV light. Current UV radiation sources are typically expensive mercury-containing gas discharge lamp, which requires high power, has a relatively short lifetime, and is bulky. Current materials absorb too much UV radiation. An international team of researchers (USA – Pennsylvania State University, University of Minnesota, Japan) found that strontium niobate films held the promise of the theoretical predictions. They successfully grew the films using sputtering. The process makes it possible to integrate this new material into UV LEDs at low cost. The technology is relevant in sanitation application, food packaging, UV photochemotherapy, and biomolecule sensing…read more. Open Access TECHNICAL A RTICLEÂ
