The prime minister's office was an accident. Baozixuan had plans before. He is going to visit Nagoya University because there is something he wants. It is also a patented technology widely used in the future. It can be said that the situation is inevitable and mistakes are not allowed.

In 1971, Jacques pengofen and ED Miller demonstrated the possibility of using zinc doped gallium nitride to make blue LEDs - although the first LED made of gallium nitride later was green. In 1972, Herbert Mallorca and Willie wynes of Stanford University and their doctoral students in materials science and engineering developed the first LED that can emit blue and purple light. The material of this led is magnesium doped gallium nitride.

Until today, magnesium doped gallium nitride is still the basic material of all commercial blue LEDs and laser diodes. However, the light emitted by the blue light diode made of magnesium doped gallium nitride is too weak to be put into practical use.

Moreover, the subsequent research on gallium nitride components has not made a breakthrough.

Until the early 1980s, at Nagoya University in Japan, Yoshiro akazaki, who was over 50, and his student Hiroshi Amano restarted the research on gallium nitride. Gallium nitride crystals that were previously considered impossible were successfully fabricated. They found that by passing an electric current into the crystal, the luminescence of the latter could be enhanced.

Subsequently, Xiuer Nakamura, an employee of Nichia chemical industry, noticed the research results of chizaki Yong's master and apprentice. He followed the research direction of teachers and apprentices, and finally produced high brightness blue LED.

The invention of blue LED is known as ”the second lighting revolution after Edison”. The invention of blue LED enables human beings to gather together LEDs that can emit three primary colors and use LEDs to gather enough bright white light. The invention of white LED lamp has greatly improved human lighting efficiency.

For such an important invention patent, since it came to Japan, of course we can't let it go.

Bao Shoufu also knows the working principle of blue LED, but he is not a professional after all, and he doesn't have the energy to study it in depth. Visible light of all colors can be synthesized from red, green and blue. Red and green light-emitting diodes have long been invented, but no one has been able to invent blue light-emitting diodes. After the successful development of blue LED, all visible light can be synthesized by LED. So that the white lighting diode later invented was invented on this basis. This significance is too great; He even won the Nobel Prize in physics.

Nagoya University, abbreviated as Nagoya University, is located in Nagoya City, Aichi Prefecture, Japan. It is one of the famous research-oriented comprehensive national universities and the highest institution in central Japan.

Mingda was founded in 1871; It was named Nagoya Imperial University in 1939; In 1947, it was officially renamed ”Nagoya University”.

The university now has 10 departments, 15 research departments, 3 research institutes, 2 national common research bases and 29 joint education and research facilities. Although it is the youngest old Imperial University in Japan, its academic achievements are by no means inferior to those of Tokyo and Kyoto universities.

Baozixuan did not inform the school, but found Professor akazaki Yong through his relationship. One of his students worked in heiyun group. It was because of this relationship that baozixuan directly came to the door.

Although Nagoya University is akazaki Yong's alma mater, he went to Panasonic electric to work for some time, and only returned to teach two years ago. Although the school gave him good treatment, the support is far from enough. Professor akazaki, who has been used to in the enterprise, has a feeling of no difference at this time.

During his tenure at Panasonic, as long as the investment is beneficial to scientific research and products, he will be allocated for the first time. But Nagoya is not only a university, but also a public university. Every appropriation is very troublesome and needs to be reviewed at all levels. In the early stage of the project, the individual income subsidy of the R & D personnel is required, and the appropriation can be obtained only after seeing the hope.

At this time, the blue LED is just a feeling and has not been paid enough attention. Nagoya University is only a symbolic investment, which can't play a big role at all.

The chairman of simultaneous interpreting group has a high reputation among the world's major universities, unlike traditional entrepreneurs. This is a talented technical boss, and his academic achievements have been recognized all over the world. Even without the halo of Xiangjiang's richest man and the president of Yulin Institute of technology, most of them will give face to invite professors from any university in the world.

Being able to communicate together is also a kind of growth; This has nothing to do with business, but more academic mutual recognition.

In a cafe near Nagoya University, Bao Zixuan met Professor akazaki Yong. He is not tall and wears a pair of golden glasses. He is dressed in a typical academic style, which can be recognized at a glance.
