I looked around a bit and I found no evidence that Alferov did work in this particular area. In particular, Akasaki, Amano and Nakamura worked on Gallium Nitride research, which Alferov doesn't appear to be involved with. Alferov did do research that is foundational in solid state physics. Alferov also won a Nobel Prize in Physics, so I don't think there is any effort to suppress his contributions.

Can you point to a place where the Nobel site is incorrect? Note that the Prize is for "efficient blue light-emitting diodes", not the first. Also if you look at this document is specifies that the work was in efficient blue LEDs and mentions earlier work on blue LEDs.

Apparently the Nobel Prize in Physics also goes to inventions. See this comment: 'Nobel Prizes in physics often go to fundamental discoveries such as the Higgs Boson. But when the committee makes an award for an invention, "we really emphasize the usefulness of the invention," said Anne L'Huillier, an atomic physics professor at Lund University in Sweden, also speaking at the press conference. And the blue LED is nothing if not useful.' (From here.)

The Nobel Prize in Physics was previously awarded for the inventions of the transistor and integrated circuits.

+ - 2014 Nobel Prize in Physics awarded to the inventors of the blue LED

grouchomarxist (127479) writes "The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, the inventors of the blue LED.

When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a funda-mental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.

They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.

White LED lamps emit a bright white light, are long-lasting and energy-efficient. They are constantly improved, getting more efficient with higher luminous flux (measured in lumen) per unit electrical input power (measured in watt). The most recent record is just over 300 lm/W, which can be compared to 16 for regular light bulbs and close to 70 for fluorescent lamps. As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.

The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.

The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.

Shuji Nakamura went on to develop the white LED and the blue laser which is used in Blu-Ray devices."

It is better to give than to lend, and it costs about the same.
