Phosphors

Phosphors

Phosphors are substances that convert energy from electron beams, electromagnetic waves, and ultraviolet photons primarily into visible light. Nichia's phosphors are used in a variety of applications, including medical applications, baggage inspection, and image intensifiers. Nichia is proud of its world-leading technology.

Nichia's Phosphor Applications

Nichia's phosphors are used in familiar situations that protect people's health and safety.


Baggage Inspection

Phosphors for X-ray are used for baggage inspection, such as security checks at airports.


X-ray Photography

Phosphors are used for medical applications, such as X-ray inspections.

Features of Nichia's Phosphor

  • High Efficiency

    Nichia's phosphor has high efficiency due to the control of impurities and internal defects as well as improved crystallinity.

  • Particle Shape Control
  • Sharp Particle Size Distribution

    Particle uniformity is achieved through synthesis and dispersion processing technologies cultivated over more than half a century of phosphor manufacturing and development. Another feature is that they are highly stability and easy to handle.



Characteristics and particle size can be discussed separately with Nichia.
