Optical emission generated by particle impact during aerosol deposition of alumina films

Aerosol deposition (AD) is a ceramic coating process that enables films to be fabricated by microparticle impact at room temperature. The optical emission during AD reported in previous studies is thought to be fracto-emission or triboemission; however, the mechanism has never been investigated in d...
