Self-Activating and Doped Tantalate Phosphors

Phosphors are useful in numerous applications including lighting. Tantalates are very promising materials because they are especially robust and resistant to chemical degradation. Studies have shown that rare-earth tantalates are excellent host lattices for europium (Eu)-doped red-emitting phosphors, excited by blue light.
