There is great potential for the development of rare earth fluorescent pigments
時(shí)間:2024-11-28

The pigment industry has always advocated for researching diverse and innovative products to meet market diversification, and many companies, like this, have made it a key focus for future development.

 

Traditional fluorescent pigments are composed of sulfides of strontium, barium, barium, or zinc. A small amount of sodium chloride (flux) and copper chloride (trace activator) are mixed and refined.

 

In recent years, China has also developed fluorescent pigments with similar advantages in rare earths. Compared to traditional fluorescent pigments, it emits higher brightness and has a afterglow time of over ten times. Especially in China, there are abundant rare earth resources with low prices, which have brought many conveniences to research and production.

 

Rare earth luminescent pigment is a type of photoluminescent pigment that utilizes the 5d-4f electron transition principle in specific rare earth elements to absorb natural light, light, ultraviolet light, etc., store energy, and release energy in the form of visible light in the dark or at night, achieving infinite repetition of the absorption luminescence process.

 

In the molecular composition, based on the activation of Eu by the original rare earth element, auxiliary activators are added from the perspective of sensitization and synergy to form trap energy levels, resulting in higher luminescence brightness and longer afterglow time of the material.

 

Rare earth luminescent pigments can be used as additives, evenly distributed in various transparent media, to achieve self luminescence function of the media, and can display the bright colors of this pigment, presenting good low-level emergency lighting, indicator signs, and decorative beautification effects. This pigment itself is non-toxic, harmless, and does not contain any radioactive elements. It has excellent stability and weather resistance, and the process of absorbing and emitting light can be repeated infinitely.

 

Fluorescent pigments have a wide range of applications. Fluorescent pigment products automatically emit bright light in the dark and are mainly used for indicating signs, decorations, etc. It can also be made into coatings, paints, inks, plastic products, etc.

 

We often see daily necessities such as switches, clocks, toys, stationery, signs, handicrafts, sports equipment, outdoor clothing, safety work clothes, etc.
