Titanates thin films

Barium titanate thin films can be deposited on various substances by treating with an aqueous solution containing barium salts and an alkanolamine-modifted titanate such as TYZOR TE (151). In a similar fashion, reaction of a tetraalkyl titanate with an alkah metal hydroxide, such as potassium hydroxide, gives oxyalkoxide derivatives (KTi O(OR) ), which can be further processed to give alkali metal titanate powders, films, and fibers (152—155). The fibers can be used as adsorbents for radioactive metals such as cesium, strontium, and uranium (156).

In addition, the BEGT thin films had larger remanent polarization and higher dielectric constant than BGdT and BEuT thin films prepared under the same experimental conditions. Therefore, co-doping of rare earth ions such as Eu and Gd in bismuth titanate thin films is an effective way to improve photoluminescence and electrical properties of the thin films. 

Recently, Pr doped ATiOs (A=Sr, Ca) titanate thin films have been widely studied for photoluminescence applications. Usually these thin films exhibit three emission peaks, which are located at 493 nm, 533 nm, and 612 nm, respectively [62], Of them, the strongest peak is at about 612 nm. It is known that the lattice distortion of host materials and/or site symmetry of rare ions greatly affect the photoluminescence properties. Since Pr doped SrTiOs or CaTiOs thin films have simple perovskite structure, whereas Pr -doped BiT (BPrT) presents bismuth layered perovskite structure, and correspondingly, site symmetry of Pr ions is...
