title: Three-photon infrared quantum cutting from single species of rare-earth Er3+ ions in Er0.3Gd0.7VO4 crystalline.
abstract: An effective three-photon IR quantum cutting excited by visible light used for solar cells, which has attracted broad attention of academia recently, is reported for the first time (to our knowledge). It is based on a single species of rare-earth Er3+ ion of Er0.3Gd0.7VO4 crystalline. It was found that the approximate quantum cutting efficiency of the 1532.5 nm 4I13/2-->4I15/2 fluorescence, when the 2H11/2 level was excited, is about 178.55%.
