1. An adapted LED comprising:

  • an LED; and

    a re-emitting semiconductor construction comprising;

    a first potential well having a first transition energy;

    an absorbing layer closely adjacent to the first potential well, the absorbing layer having a band gap energy greater than the first transition energy and smaller than an energy of a photon emitted by the LED; and

    a support layer substantially transparent to light emitted by the LED and the re-emitting semiconductor construction and disposed between the first potential well and the LED.
