Crystallographic site engineering of a single Bi 3+ -doped single-component Ca 5 Ga 6 O 14 :Bi 3+ phosphor for full-spectrum white light emission and highly sensitive optical thermometry

High-quality full-spectrum white emission and highly sensitive ratiometric thermometry are simultaneously achieved in a single Bi 3+ -doped, single-component phosphor, Ca 5 Ga 6 O 14 :Bi 3+ , through the implementation of crystallographic site engineering.
