People are becoming more concern to the global warming matter, as the scientists have been given out warning that when the entire icebergs in Arctic had totally melt down, then the sea level will rise up to 7 meter high permanently!
In order to slow down the icebergs’ melting speed, many inventors have been tried to invent the green yet environmental friendly products. Well, you’ve probably heard your neighbors or friends said, where they’ve already changed their house lighting system, from the compact fluorescent lights to the energy-efficient LEDs lights!
The LEDs, especially the organic LEDs, are becoming increasingly popular in these days. For your information, the organic LEDs are mostly thin films made from organic polymers. It can be easily coated onto large areas at a very low cost.
Soo-Young Park, from Seoul National University, South Korea and his colleagues at the University of Valencia, Spain has built a molecule, which is able to behave like two separate light-producing molecules.
“It produces orange and blue light, when it stimulated with a voltage. The mix of orange and blue light will turn into white,” said Park.
This means, with this technology, it allows the manufacturers to create white emission in much the same way, as creating white light from independent lights. In this case, we’re not only can save much money, but it greatly reduces the carbon offset too! [newscientist]
