UV-Phosphor Powder Description
UV-Phosphor is also known as ultraviolet fluorescent powder. This powder comprises metal sulphide (Zinc, Cadmium) or rare earth oxide combined with micro surfactants and is produced by calcination. Given that the wavelength of the light source varies, it is classified as short-wavelength UV-Phosphor (excitation wavelength of 254 nm) and long-wavelength UV-Phosphor (excitation wavelength of 365 nm).
UV-Phosphor Powder Features
- The particles are small and spherical, dispersing readily with a diameter of approximately 1–10 μm.
- The material withstands temperatures up to 600°C, thereby accommodating high temperature processing.
- It exhibits resistance to solvents, acids, and alkalis, and it maintains high stability.
- It does not migrate or cause contamination.
UV-Phosphor Applications
- It is used as a substitute for 260 nm low-pressure mercury lamps for sterilisation and for the treatment of skin diseases.
- It is employed in the manufacture of anti-counterfeit ink and anti-counterfeit paint.
- It is utilised in product quality assessment.
