«Let there be light .. . gallium nitride on! “certainly cried once inventor LED lamp with blue luminescence Shuji Nakamura. Alternative bulb Ilyich – ordinary incandescent lamp was more than convincing. It was a real revolution in lighting: ten times more energy efficient, safe and economical. And because the presentation of Nakamura and his colleagues Hiroshi Amano and Isamu Akasaki Prize Alfred Nobel is fully consistent with the will of the great patron of the arts: to award the prize to “who for the past year has brought the greatest benefit on mankind.” Agree, it is more targeted assistance than the discovery of the ephemeral Higgs boson, for which was given the Nobel last year.

And let the concept – “the past year” in this case stretched to 20 years, the grateful descendants still proved that the authors have not forgotten the most effective light source and illumination of our wide variety of gadgets.

In fairness at the moment you can remember about the Russian scientist Alexey Losev – theorist electroluminescence. He first discovered the glow effect of the inorganic material under stress. Later were invented green and red LEDs, but they were not suitable for lighting. Isamu Akasaki namely in 1989 created a blue glow diode based on gallium nitride. And in 1994, Shuji Nakamura created the first blue LED that can be inserted into the already nice cat.

– If you’re familiar with the spectrum of visible light, then you already know that the blue – the shortwave – explains to us the essence of the opening Head of the Department of luminescence them. SI Vavilov FIAN’s Doctor of Physical and Mathematical Sciences, Professor Alexei Vitukhnovsky. – So, putting on the surface of gallium nitride various phosphors (a substance capable of converting absorbed their energy into light – Auth. ) is made possible to easily create any color LED bulbs and primarily white, suitable for lighting. The white color was obtained by combining blue and yellow.

The Chinese are spending their Olympics in 2008 were proud that used to light stadiums, gyms only LEDs. Companies that create mobile phones use LED screens for phones, fighting for brightness and higher contrast. There is also a need to provide LEDs that provide light resembling the solar more. In this regard, there was also a new direction in the luminescence – the creation of organic light-emitting diodes, and what we are doing in our laboratory.
