In view of the steady improvement of the performance of Intematix's phosphors in the United States, the market share has expanded rapidly. In particular, South Korea's Samsung has recently launched LED-backlit TVs, and a large number of Intematix patented phosphors have been used. Itematix products now have a high market share.
Intematix Dr. Liu Xiao, General Manager of Shenzhen Intemet Optoelectronics Co., Ltd. (hereinafter referred to as Dr. Liu) introduced that Intematix Headquarters was established in 2000 in California, USA. The company is mainly invested by several large US venture capital companies, including Samsung in South Korea. Occupy an important share in the company. The company has 70-80 employees, but the doctors account for nearly 30 people. The company was engaged in some energy, medical, and nanomaterial research projects of the US Department of Energy and the Department of Defense. Its patented silicate phosphors have been widely used in the rapid development of commercial LEDs in the past few years. They not only have excellent performance, but also have independent intellectual property rights. They have applied for dozens of patents in the United States.
Intematix started to build and establish several subsidiaries after 2007, including Taiwan Inter Mingguang Energy Co., Ltd., Suzhou Intertek Lighting Co., Ltd., and Shenzhen Inteome Optoelectronics Co., Ltd. - as the Intematix Group and its subsidiaries. China's business and operation center, the rapid development of the company, quickly made Intematix become the world's leading manufacturer of optoelectronic materials with unique technology.
Core technology drives the development of Intematix phosphors
Dr. Liu introduced that Intematix has a unique material research technology. The technology itself is also patented in the United States. Simply put, this material research and development technology can simultaneously apply chemical materials to hundreds or even thousands of different components. Conducting research and testing has greatly shortened the time for material development (shown in Figure 1 below). Because phosphor chemistry contains many elements and doping, if you want to find the best components and combinations, you have to carry out numerous experiments and spend a lot of manpower and time. Intematix's patented material research and development technology can be used by others. The work that can be completed in years or even years is shortened to one or two months, which is the key to Intematix's product performance. Intematix phosphors are not only excellent in performance, but also have extensive patent protection, and many of the world's largest packaging plants, including many mainland China packaging plants, many have Intematix patent license.
In general, LED phosphors have several major branches. First, Nichia's YAG doping with rare earth Ce is the most patented patent for LED white light packaging. Nichia has also filed lawsuits against a number of companies that infringe on its patents. Although YAG materials have existed for a long time, the production of YAG materials itself does not constitute infringement, but it can be said that the use of YAG phosphors for white LED packaging is on the right day. The Asian patent was infringed. In response, Osram has developed TAG phosphors. Although it is the same as the aluminate, because the TAG uses the element (TB) instead of the element (Y) in the YAG, it has successfully avoided the special image of Nichia. In response, OSRAM has licensed TAG phosphor-packaged white LEDs to several leading packaging companies in Taiwan and South Korea, enabling these companies to legally produce and sell white LEDs.
But unfortunately, the performance of TAG phosphors is far less than that of YAG, and the light efficiency is also far from the same. There has been no major breakthrough in production and research for many years, which limits the application of TAG phosphors. So many customers with Osram TAG licenses are now using Intematix phosphors.
The other two branches of the patented phosphor are Japan's Toyota Synthetic and Intematix's silicate series. The silicate series phosphors are completely different from YAG and TAG, not only with different host materials, but also with different particle sizes and doped rare earth elements. Also different (Eu instead of Ce). Intematix's silicate phosphors are different from those of Toyota Synthesizers. They are somewhat similar to YAG and TAG. Although they are the same as silicates, the silicates of the two companies have different main components, and the components of the doped and substituted silicates. It is also different, and it is these differences that make the performance of Intematix silicate phosphors greatly improved and are widely used by businesses.
