glow in the dark material characteristics

In the glow in the dark material in the field, the study of organic materials increasing people's attention. Because many types of organic compounds,photoluminescent exit signs glow pigments adjustable, good, rich colors, high color purity, molecular design is relatively flexible. Depending on the molecular structure of the organic light emitting material can be divided into: (1) an organic small molecule light emitting material;glowing stone pebbles (2) an organic polymer light-emitting material;glow in the dark sand (3) an organic luminescent material complexes. These luminescent material emitting mechanism in terms of physical and chemical properties, or in the application on has its own characteristics.
