据我们所知，最近首次报道了一种利用可见光激发的有效的三光子红外量子切割技术，用于太阳能电池，引起了学术界的广泛关注。它是基于单一种稀土Er3+离子的Er0.3Gd0.7VO4晶体。发现1532.5 nm 4I13/2—>4I15/2荧光在2H11/2能级激发时的量子切割效率约为178.55%。
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%.
