Main factors affecting the luminescent properties of luminescent powder

With the increasing use of luminescent powder in the market, the pigment can be used to make luminescent products, and its luminescent property is a common concern of users. What factors affect the luminescent properties of luminescent powder? The following is a brief introduction to the main factors affecting the luminescent properties of luminescent powder.

1. The luminescent properties of luminescent materials are closely related to the type of crystal structure of the material matrix and the type and quantity of luminescent center stimulating agent ions, and are also affected by process technologies and processes such as material synthesis processing.

2. The particle size of the luminescent powder is the main factor affecting the luminescent properties. An excessively large particle diameter is detrimental to the light absorption and emission of the luminescent center, and is difficult to disperse uniformly and remain stable in the preparation of the coating, thereby lowering the coating quality. However, if the particle size is too small, agglomeration tends to occur, resulting in uneven dispersion of the luminescent center, affecting the luminous efficiency, and causing the afterglow time not to be long, resulting in afterglow quenching.

The above contents mainly introduce the main factors affecting the luminescent properties of luminescent powders. I hope that they can be helpful to everyone and easy to understand.
