Scintillators are materials that emit light when excited by radiation, such as X-rays and gamma rays. They are used for various application including CT scanners, security devices and non-destructive testing.
Toshiba Materials develops and manufactures high-light-output and low-decay-time scintillators with our leading technologies for fine ceramics manufacturing and fluorescent material design.
Features
- High light output, low decay-time and low afterglow.
- Flexibility to your design and purpose.
- Contains no toxic or hazardous substances.
- Excellent in humidity resistance.
