中文Characteristics of plastic luminous agent
The remarkable characteristics of metal sulfide system are rich luminescent colors, which can cover the luminescent region from blue to red; The disadvantage is that Unstable chemical properties, low luminous intensity and short time. The characteristics of rare earth aluminate luminous agents are as follows ① High luminous efficiency. Aluminate luminous agents have high quantum efficiency in visible light region, and are used in plastics. The amount is small, which is beneficial to reducing the manufacturing cost of luminous plastics. ② Long luminous time....
