Crystal phase induced upconversion enhancement in Er/Yb doped SrTiO ceramic and its temperature sensing studies.

Spectrochim Acta A Mol Biomol Spectrosc 2019 Apr 28;212:78-87. Epub 2018 Dec 28.

Through doping of Er/Yb ions the SrTiO perovskite ceramic is turned into an optically active material keeping its ferroelectric property intact. A huge enhancement of around 20 times in upconversion (UC) emission intensity is observed due to the transformation of cubic crystal structure to tetragonal phase. The intensity ratio of green to red band is found too high to neglect the contribution from the red emission band, which is not observed normally in such type of relatively moderate phonon frequency materials containing Yb/Er ions. The change in emission intensity is reflected in the decay time measurement. Optical temperature sensing behavior based on FIR technique also has been discussed for Er/Yb doped SrTiO ceramic.
