What is Shuji Nakamura famous for?
Shuji Nakamura, (born May 22, 1954, Ehime, Japan), Japanese-born American materials scientist who was awarded the 2014 Nobel Prize in Physics for inventing blue light-emitting diodes (LEDs). He shared the prize with Japanese materials scientists Akasaki Isamu and Amano Hiroshi.
Who got Nobel for LED?
Isamu Akasaki, a Japanese physicist who helped develop blue light-emitting diodes, a breakthrough in the development of LEDs that earned him a Nobel Prize and transformed the way the world is illuminated, died on Thursday in a hospital in Nagoya, Japan. He was 92.
Who made the first blue LED?
Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura made the first blue LEDs in the early 1990s. This enabled a new generation of bright, energy-efficient white lamps, as well as colour LED screens.
Who invented the white LED?
Jürgen Schneider, former head of department at Fraunhofer Institute for Applied Solid State Physics and inventor of the white LED, celebrates his 80th birthday at 25.11.
Who invented blue laser?
inventor Shuji Nakamura
In 1992 Japanese inventor Shuji Nakamura invented the first efficient blue LED, and four years later, the first blue laser.
Who invented red LED?
Nick Holonyak, Jr.
The next year, in 1962, Nick Holonyak, Jr. (the “Father of the Light-Emitting Diode”) invented the first LED that produced visible, red light while working at General Electric. Throughout the 1960s, researchers and engineers continued experimenting with semiconductors with the goal of producing more efficient LEDs.

Why did blue LEDs win a Nobel Prize?
That year, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics to three scientists—Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura—“for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources.” Never before had researchers working so …
When was green LED invented?
1958
1927- Russian inventor Oleg Lesev reports the creation of the first LED. Publishing theories on his findings. 1952- Professor Kurt Lechovec tests some of Losevs theories, he goes on to explain the first light-emitting diodes. 1958- Egon Loebner and Rubin Braunstein create the first green LED.
Is there a true white LED?
LEDs do not directly produce white light. There are two ways in which white light is produced from LEDs as below: Using a blue LED with a phosphor coating to convert blue light to white light by a process called fluorescence. Combining red, blue and green LEDs to produce white light.
Can you make a white laser?
No one has been able to create a laser that beams white light. Researchers at Arizona State University have solved the puzzle. They have proven that semiconductor lasers are capable of emitting over the full visible color spectrum, which is necessary to produce a white laser.
