Abstract
A first-order quantum cutting luminescence of couples, which are incorporated in the nanocrystals embedded in transparent glass ceramic, is reported for the first time, to our knowledge. When is excited with one blue photon, it was experimentally demonstrated that the resonant energy transfer from to occurs, leading to the near-infrared quantum cutting with one photon emitting at and one photon at . The theoretical quantum efficiency is evaluated to be 159%.
