Scientists from Seoul National University and the University of Valencia have discovered a single molecule that reliably emits white light which could speed the development of low-energy LEDs for the next generation of light sources and displays. BLT Direct, the leading online providers of mercury lamps, halogen light bulbs and light fittings, believe that energy efficient LEDs are likely to become the main source of lighting over the next ten years replacing both the incandescent bulb and compact fluorescent lights.
The researchers have created a molecule which is able to behave like two separate light-producing molecules. When stimulated with a voltage it produces orange and blue light that mix to create white. This allowed the scientists to create a white light in much the same way as creating white light from independent lights which will potentially save money and increase efficiency.
Previous attempts using the same basic concept have been unsuccessful as energy was able to flow between the two molecules. As one molecular sub-unit typically emitted more light than the other, an unwanted tint resulted. BLT Direct, who also offer a range of light bulbs and energy efficient light bulbs are excited by these findings although they point to the fact that these new LEDs work at least thirty times less efficiently than existing commercial LEDs. In order for them to become widely available the efficiency of these new LEDs will need to be improved significantly.
