Abstract

Simultaneous ferroelectric and optical properties are present in transition metal Ni2+-doped perovskites BaxSr1-xTiO3. Large tuning of near-infrared (NIR) photoluminescence is achieved by chemical substitution due to the variation in the crystal field acting on Ni2+doping ions. The prepared materials show ultrabroadband NIR luminescence, from 1100 nm to over 1600 nm. The peak position of the NIR emission can be finely tuned, and a total shift of 269 nm was observed. The mechanism behind the observation is discussed; the interestingly tunable luminescence originates from a change in the specific structure of the ferroelectric matrix.
