Rare earths and the field of optoelectronics

Humans fear darkness and yearn for light. From the torches of ancient times to the dazzling and colorful lights of today, rare earths have played an extraordinary and significant role on this path of seeking and creating light.

I. Advantages of rare earth luminescent materials in the field of optoelectronics

mainly include: narrow emission spectrum, high color purity, strong light absorption capacity, high conversion efficiency, wide emission wavelength distribution range, high physical and chemical stability, as well as good coating performance and heat resistance, capable of withstanding the effects of high-power electron beams, high-energy radiation, and strong ultraviolet light.

II. Main Application Areas of Rare Earth Luminescent Materials

Lighting field: Fluorescent lamps, high-pressure mercury lamps, black light lamps, solid light sources; Display imaging field: Light-emitting diodes (LED), televisions, computers, large-screen projectors; Medical X-ray field: X-ray instruments used in fracture or health check-ups; Industrial X-ray field: X-ray detection instruments used for inspection of welding parts in ships, pipelines, etc.

III. Future Prospects of Rare Earth Luminescent Materials

The application of rare earth luminescent materials will bring environmental protection, energy saving, good color rendering performance and long service life to light sources, which is conducive to promoting the upgrading of products in the lighting and display fields. Currently, China's rare earth luminescent materials industry closely follows the development trend of international research and application of rare earth luminescent materials, and has established a good market interaction mechanism with the downstream industries. It has become an indispensable basic material in the development process of energy-saving lighting and information electronics industries.
