Luminescent impurity ion probe and low temperature phase of SrTiO3 nanoparticles
Original language description
Photoluminescence of Cr3+ impurity ions was studied on nanocrystalline SrTiO3:Cr(0.1%) powders with an average particle size between 13 and 100 nm. The position of the zero-phonon emission R-line of the octahedral Cr3+ centres shifted to higher energieswith decreasing particle size. The temperature shift of the R-line position appeared for all powders nearly the same as the 'dielectric related' one in the bulk crystals, evidencing that SrTiO3 retains quantum paraelectric behaviour down to a particle size of about 10 nm.
