Blue LED won Nobel Prize

Beginning this week, the Nobel Prize in Physiology/Medicine and the Prize for Physics have made their debut, and scientists have won world-renowned awards for their research on brain cell location systems and blue laser diodes (LEDs). While solving the difficult problems of scientists and even philosophers, they also brought about tremendous changes in human life.

This year's Nobel Prize in physics was awarded to energy-related research. Japanese scientists Akaki Yoshihide, Amano Amano, and Japanese-American scientist Nakamura, who won awards for inventing blue light-emitting diodes (LEDs), gave them the reason that they had brought new energy-saving light sources.

As the emergence of incandescent and fluorescent lamps was seen as a major breakthrough in the lighting industry, when the three scientists produced a bright blue beam in the early 1990s, this technology also brought a historic revolution in lighting technology. . Although red LEDs and green LEDs have been invented for a long time, the manufacture of blue LEDs has been a major problem for a long time. Because of the lack of blue in the three primary colors, white LED light sources that can be used for illumination cannot be obtained.
