Saphlux receives $5 million to finance a new generation of luminescent materials to take a vector or "near-foot"
Today, Saphlux founder Chen Chen revealed that the project was approved by Liard on February 14th, and the investment of 5 million US dollars in the A-fund, Elm Street and NXT will be used for the next generation of nitriding. Mass production of potassium luminescent materials and development of applied products. In September last year, Pencil Road reported on the project (“With a piece of material, I got $1.5 million to invest in lighting that solved the physics problem with 10 times brightnessâ€). At that time, the team won a $1.5 million angel round investment with a luminescent material that could bring ten times the brightness, and technically solved the mass production problem of large-size semi-polar potassium nitride materials. Once the product was launched, three of the world's top five LED manufacturers were adopted. Chen Chen’s heart is white, which is both a milestone and a turning point. Real industrial production is still a long way forward. At that time, the team relied on laboratory equipment, and the machine could produce a piece of potassium nitride luminescent material once. It can only produce a few pieces a day, and the price is about 560 US dollars, which is far from meeting the commercial needs. Going forward, you need capital blessing. Hard technology is like a protracted war, and you have to be patient. We want to establish high enough technical barriers and the simplest business model. Note: Chen Chen promises that the data in the text is correct and responsible for its authenticity. Out of the laboratory's potassium nitride luminescent materials Since the development of blue LEDs in Nakamura Shuji in the 1990s, solid-state display illumination with the first generation of semiconductor luminescent materials as the core has gone through more than 20 years, and its brightness has reached its limit. Scholars want to be brighter. Semi-polar potassium nitride luminescent materials have theoretically proven to be ten times brighter than in the past. But it can't be mass-produced, making it only the darling of the lab. This situation improved in May last year. Founded in Yale, the Saphlux startup has technically realized the mass production of potassium nitride luminescent materials, which can be 2 inches, 4 inches and 6 inches in size. Once the news was exposed, large companies in the LED industry, as well as governments and research institutions, came to the door. One of the orders made the team extremely excited. The e-mail was sent from UCSB (University of California, Santa Barbara), and was sent by a highly respected professor in the K2 research room of Nakamura Shuji. The first sentence in the text is congratulations. Large-scale, semi-polar potassium nitride materials without stacking faults are difficult problems that they have not solved, and are the key to turning on the next generation of semiconductor lighting materials. The LED samples that the team lit up were delighted and the team was helpless. The orders sent by the company are hundreds of pieces, and Chen Chen can only try to send two pieces of the first. At that time, the team's research and development equipment was only an experimental single-chip device. Only one piece of potassium nitride luminescent material could be produced in one furnace. Even if it is non-stop, it is far from meeting the industrial production demand. From the project line to the turning point, in order to explore industrial mass production, it is necessary to integrate money. A new device costs one or two million dollars. Hard technology is not like a lot of software companies, tightening the belts, everyone can get a little less wages for a while, to get equipment, you have to ask for money.
