The rare earth luminescent materials industry develops rapidly and the competitiveness of local enterprises increases

Rare earth luminescent materials are rare earth functional materials, which refer to luminescent materials using rare earth elements as activators. There are many kinds of rare earth luminescent materials. According to different excitation sources, they can be divided into triboluminescence, electroluminescence, radioluminescence, cathode luminescence, photoluminescence materials, etc.

The main raw materials of rare earth luminescent materials are rare earths. my country accounts for 80.0% of the identified global rare earth resources. According to statistics from the United States Geological Survey (USGS), my country’s rare earth production reached 168,000 tons in 2021, a year-on-year increase of 20.0%. The advantages of raw materials have driven the rapid development of the rare earth luminescent materials industry. At present, my country has become the world’s largest producer of rare earth luminescent materials. According to statistics from the China Rare Earth Industry Association, my country’s total output of rare earth luminescent materials will reach 1,791.5 tons in 2021.

The production of rare earth luminescent materials requires raw material pretreatment, screening of ingredients, sintering ingredients, surface treatment and other processes. The preparation methods include sol-gel method, high temperature solid phase method, precipitation method, hydrothermal method, spray pyrolysis method, etc. The high-temperature solid-phase method refers to mixing raw materials and ingredients under high-temperature conditions, and then going through processes such as cooling, crushing, and sieving to finally produce rare earth luminescent materials. The high-temperature solid-phase method has the advantages of simple operation and high luminous efficiency of the product, and is a common preparation method for rare earth luminescent materials.

According to the “2022-2027 China Rare Earth Luminescent Materials Market Feasibility Research Report released by the Industrial Research Center, according to different uses, Rare earth luminescent materials can be divided into three types: special rare earth luminescent materials, rare earth luminescent materials for display and rare earth luminescent materials for lighting. Currently, rare earth luminescent materials for lighting are the mainstream products. Rare earth luminescent materials have the advantages of good color rendering, high luminous efficiency and long service life. They can be used to make LED lights and are widely used in automotive lighting, shopping mall lighting, traffic lights and other fields. In 2021, my country’s demand for rare earth luminescent materials for lighting will reach 1,300.0 tons, accounting for 70.0%.

The main manufacturers of rare earth luminescent materials in my country include Zhejiang Minghui Luminescent Technology Co., Ltd., Shanghai Keyan Optoelectronics Technology Co., Ltd., Jiangsu Tiancai Technology Materials Co., Ltd., Dongguan Anda Rare Earth Luminescent Materials Co., Ltd., and Jiangmen Keheng Industrial Co., Ltd. In recent years, my country’s rare earth luminescent material manufacturers have continuously increased their investment in research and development and have gained competitive advantages in the global market. Among them, Keheng Industrial’s production technology has reached the world’s advanced level.

Industry analysts said that rare earth luminescent materials have the advantages of strong emission capabilities, strong absorption capabilities, and high luminous efficiency. They are used in X-ray light-enhancing screens. , new light sources, LED lighting and other fields are widely used. As the concept of green environmental protection continues to deepen, rare earth luminescent materials will gain broad market space as energy-saving materials. my country is the main producer of rare earth luminescent materials, and local companies have core competitive advantages in the global market.
