ABSTRACT:
Zinc Oxide is an extensively studied group II-VI semiconductor with optical properties that permits stable emission at room temperature having immense application in sensors, field emission and photonic devices. It exhibits a wide variety of morphologies in the nano regime that can be grown by tuning the growth habit of the ZnO crystal. ZnO nano materials doped with Cerium ions XRD, SEM, FTIR, TEM and EDS characterized the samples. The percentage of doping material is confirmed from the EDS spectra. The average crystal size of the prepared ZnO nanopowder is determined by XRD. The size of the particles increased as the annealing temperature was increased. The crystallite size varied from 13nm to 16 nm as the calcination temperature increased, are synthesized by chemical route technique. Ultrasonic velocity through doped and undoped sample is measured and compressibility is computed. The compressibility is found to be increased. Also variation of compressibility of ZnO: Ce nanofluid with various grain size have been carried out and found that compressibility increases with decrease of particle size. To study the elastic properties of the nano fluid extensively, certain important physical parameters such as adiabatic compressibility, specific acoustic impedance, relative association, intermolecular free length, Rao’s constant, Wada’s constant etc. are evaluated using ultrasonic velocity and density.
