Det menes, at nye højeffektive lysdioder kan anvende [[kvanteø]]er til effektivt(55-100%) at omsætte UV-lys til fuldspektret hvidt lys.<ref>[http://www.sciencedaily.com/releases/2004/06/040623083024.htm Sandia National Laboratories (2004, June 23). Wireless Nanocrystals Efficiently Radiate Visible Light. ScienceDaily] Citat: "...The efficiency of the energy transfer from the [[Kvantebrønd|quantum well]] to the [[Nanokrystal|nanocrystals]] was approximately 55 percent – although in theory nearly 100 percent transfer of the energy is possible and might be achieved with further tweaking...The work is another step in creating more efficient white-light-emitting diodes..."</ref><ref>[http://www.sciencedaily.com/releases/2005/05/050518200912.htm Los Alamos National Laboratory (2005, May 18).
