January 2021, backup Citat: "...[papirside 17-18 (pdf-side 30-31)] The luminous efficacies for Product MS-4 DUTs when the 2,700 K and 5,000 K settings were used during AST are shown in Figure 3-13a and Figure 3-13b, respectively. During RTOL, luminous efficacy initially increased with use during RTOL because of a small (3% to 4%) drop in power consumption that occurred during the first 1,000 hrs of operation..."

19/08/01, ing.dk: Første hvide lysdiode Citat: "...Effekten skyldes en særlig form for eksitation først opdaget i 1994...De resulterende elektron-hul par, der nu omfatter begge molekyler, henfalder ved udsendelse af fotoner, hvis bølgelængder dækker hele det synlige spektrum... levetid vil være mange gange større end elektriske pærers...(App. Phys. Let. 30/7-01)"

Sandia National Laboratories (2004, June 23). Wireless Nanocrystals Efficiently Radiate Visible Light. ScienceDaily Citat: "...The efficiency of the energy transfer from the quantum well to the 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..."
Los Alamos National Laboratory (2005, May 18). Scientists Develop Novel Multi-color Light-emitting Diodes. ScienceDaily Citat: "...semiconductor nanocrystals are incorporated into a p-n junction formed from semiconducting GaN injection layers. The new LEDs utilize a novel type of color-selectable nanoemitters, colloidal quantum dots, and makes use of emerging GaN manufacturing technologies..."

soton.ac.uk: The life and times of the LED — a 100-year history Citat: "...Many people believe that the LED was dicovered by US researchers working in the 1960s. In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago and, independently, a forgotten Russian genius — Oleg Losev — discovered the LED..."

Breakthrough Technology Accelerates Solid-State Lighting Citat: "...The industry has set a target for white LEDs to reach 150 lumens per watt (lm/W) by the year 2012. The new SPE LEDs, under certain operating conditions, are able to achieve more than 80 lm/W, compared to today's typical compact fluorescent lamp at 60 lm/W and a typical incandescent lamp at 14 lm/W..."
