The market space for quantum dot luminescent materials continues to grow, and my country is in a leading position in the world

Quantum dot luminescent material is a luminescent material with excellent performance. It has high color purity, high photostability, wide absorption spectrum, narrow emission spectrum, full spectrum luminescence, continuously adjustable peak position, large Stokes shift, and fluorescence lifetime. Long and other advantages, different colors can be produced by changing the size of quantum dots. Quantum dot luminescent materials have broad application prospects in new displays, life sciences, optoelectronics, energy and other fields. Especially in new display fields, they are expected to replace traditional phosphors.

In the LED field, rare earth phosphors are mainly used as luminescent materials. As the scale of the LED industry continues to expand, the demand for rare earth phosphors continues to rise. Global LED production capacity is being transferred to mainland my country. Attracted by profits, the number of Chinese companies entering the field of rare earth phosphors is increasing. Under fierce competition, corporate profitability continues to decline, and it also causes a waste of rare earth resources. Quantum dot luminescent materials can be used to manufacture quantum dot panel QLEDs, which have excellent display effects. Therefore, quantum dot luminescent materials can replace traditional phosphors.

Since 2015, Chinese and foreign manufacturers such as TCL, Samsung, Hisense, Huawei, and Xiaomi have successively launched QLED TVs, and the market space for quantum dot luminescent materials is constantly increasing. Compared with rare earth phosphors, the cost of quantum dot luminescent materials is higher, and the stability and reliability of combination with LEDs are still insufficient. In the future, as technology continues to improve and costs continue to decrease, quantum dot luminescent materials and rare earth phosphors, etc. Luminescent materials will dominate different market segments with their own advantages, and the coexistence of multiple luminescent materials will exist for a long time.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on Quantum Dot Luminescent Materials Industry 2021-2025” released by the Industrial Research Center, Globally, the United States, China, and South Korea are the main countries deploying quantum dot luminescent materials. From the perspective of patent applications, China and the United States have the largest number of patent applications. Related research universities, institutions and companies mainly include MIT, Berkley, QD Vision, etc. in the United States, and Zhejiang University, Nanocrystal Technology, etc. in China. South Korea basically has no core patents on quantum dot luminescent materials, and Samsung has made arrangements by acquiring QD Vision. From the perspective of manufacturing companies, the global suppliers of quantum dot luminescent materials are mainly American Nanosys, American QD Vision, and Chinese Nanocrystal Technology.

Industry analysts said that from the perspective of our country, Zhejiang University is a global leader in the field of quantum dot luminescent materials research, and is comparable to nanocrystals. Technology jointly builds laboratories to jointly develop products. Nanocrystal Technology is one of the few companies in the world with the ability to mass produce quantum dot luminescent materials. It has already supplied panel manufacturers such as TCL and Hisense. Whether from the perspective of technical research or industrial development, my country’s quantum dot luminescent material industry is in a leading position in the world. In the future, the scale of the QLED market will gradually expand, and the representative company Nanocrystal Technology will benefit first.
