Optimization of magneto-electric properties in Lead-free (x)Co1.2Ti0.2Fe1.6O4 - (100-x)BaTiO3 based composites
Rajeev Dwivedi, Samanway Mohanta, Ashutosh Anand +7
This work presents a systematic study of lead-free multiferroic composites of (x)Co1.2Ti0.2Fe1.6O4 - (100-x)BaTiO3 (x = 10, 20, 30), which were synthesized by a solid-state reactio…
Metal Cluster's Effect on the Optical Properties of Cesium Bromide Thin Films
Kuldeep Kumar, P. Arun, Chhaya Ravi Kant +1
Cesium Bromide films grown of glass substrates by thermal evaporation showed interesting optical properties. The UV-visible absorption spectra showed peaks which showed red shift w…
Film Thickness controlled photoluminescence Emission in ZnO:Si Nano-composites
Shabnam, Chhaya Ravi Kant, P. Arun
As grown ZnO:Si nanocomposite films fabricated by thermal evaporation showed broad photoluiminescence (PL) spectra due to merging of four prominent peaks viz 370, 410, 470 and 520…
White-Light Emission from Annealed ZnO:Si Nanocomposite Thin Films
Shabnam, Chhaya Ravi Kant, P. Arun
As grown ZnO:Si nanocomposites of different compositional ratios were fabricated by thermal evaporation techniques. These films were subjected to post deposition annealing under hi…
Size and Defect related Broadening of Photoluminescence Spectra in ZnO:Si Nanocomposite Films
Shabnam, Chhaya Ravi Kant, P. Arun
Nanocomposite films of Zinc Oxide and Silicon were grown by thermal evaporation technique using varying ratios of ZnO:Si in the starting material. Analysis reveal the role of ZnO a…
Characterization of ZnO:Si Nanocomposite Films Grown by Thermal Evaporation
Shabnam Siddiqui, Chhaya Ravi Kant, P. Arun +1
Nanocomposite thin films of Zinc Oxide and Silicon were grown by co-evaporating powdered ZnO and Si. This resulted in nanocrystallites of ZnO being embedded in Silicon. The mismatc…
