Gadolinium Nitrate is used for making optical glass and dopant for Gadolinium Yttrium Garnets which have microwave applications, also applied in special catalyst and phosphors.
Gadolinium Nitrate is also used for making green phosphors for color TV tubes.
It is used in many quality assurance applications, such as line sources and calibration phantoms.
