A venture of Japan National Institute for Materials Science
NIMS have developed various phosphors, including Sialon, SCASN, AlN …
1. Standard phosphor
3kg single production lot for each color
5g×3 colors per set
3. PL/PLE spectra and QE values
Sialon phosphor, which mainly composed by elements of Si-Al-O-N, can emit different color when the component changes. It is very chemically stable and durable. The luminous intensity is also stable even under high temperature. It is widely used in white LED.
5. Application of Standard phosphor
- As a reference for calibration of QE measurement
- As a reference for LED phosphor maker
