Characterization and Elastic study on Zinc Sulphide Nanofluid Doped with Neodymium

Abstract

Among the Semiconductor nanoparticle ZnS as an important II-VI semiconductor has been researched extensively because of the broad spectrum of potential application such as catalysis, cathode ray tube (CRT), field emission display (FED) phosphors for a long time. It can be used for electroluminescent devices and photodiodes. Zinc sulphide doped with Neodymium (ZnS: Nd) quantum dots have various applications in electronics, nonlinear optical devices and optical computers. ZnS: Nd nanomaterials with an average particle size of 21-25 nm are synthesized by the reaction of zinc acetate and hydrogen sulphide by chemical route technique. XRD, SEM, FTIR and EDS characterize the samples. The percentage of doping material in the crystal is confirmed from the EDS spectra. The average crystal size of the prepared ZnS nanopowder is determined by XRD. 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 ZnS: Nd nanofluid with various grain size have been carried out and found that compressibility increases with decrease of particle size.
