In this work, TiO2 nanoparticles doped with holmium (III) ion have been prepared by an ultrasonic assistant sol-gel method. We present the results of the investigation of holmium (III) ion doping on the structural properties of TiO2 and its effect on the anatase to rutile phase transformation. It is found that the transformation temperature, measured from the XRD experiments, is found to increase...
Zinc oxide is a versatile material that has achievable applications in piezoelectric transducers, nanogenerators, transparent electrodes and etc. Currently, sonochemical processes have been proved to be a useful technique for generating various nanostructured materials. In this work, we have developed a method for the synthesis of ZnO nanostructures, by combining the advantages of both ionic liquid...
The photoacoustic (PA) spectra of Eu 3+ -La 3+ -Hba complexes are reported (Hba: benzoic acid). It is found that the PA intensity of the ligand bears a relation to the energy transfer processes. For Eu 3+ -La 3+ -Hba coprecipitates, with increasing the concentration of La 3+ , the PA intensity in the region of the ligand absorption decreases...
