Luminescence studies of Yttrium and Cerium
ISBN: 9786206767602 / Angielski / Miękka / 164 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Photoconductivity is the phenomenon of enhancement of conductivity due to irradiation of light photons. Further, photoluminescence is the phenomenon of emission oflight in the visible or near visible region due to excitation of light photons. Both these phenomena involve processes like excitation, recombination and trapping of carriers etc. The present thesis is concerned with mainly photoconductivity and photoluminescence studies of (Cd- Pb )S : CdC12 ,Y ICe films prepared by chemical deposition technique. Results of optical absorption spectra, XRD and SEM studies are also presented for...

Perovskites With Nanoparticles For Solar Cell Applications
ISBN: 9786206782889 / Angielski / Miękka / 248 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The CsPbBr2Cl and composite CsPbBr2Cl:ZnO thin films were fabricated via low-temperature, solution-processed full doctor blade method. The surface morphology and crystallinity of the synthesized thin films were investigated by XRD, SEM and EDX. UV-Visible and photoluminescence measurements were performed to study the optical properties of the synthesized thin films. The composite system showed red shift and comparatively smaller bandgap with sharp PL emission, which can be attributed to the formation of CsPbBr2Cl:ZnO. Compositional analyses of prepared films were analyzed by FTIR analysis....

Electro-Optical studies of Nanocomposites
ISBN: 9786206779247 / Angielski / Miękka / 168 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This work is for a basic understanding about the synthesis process of ZnO structures like nanoparticles (NPs) and nanowires (NWs). ZnO NPs and NWs have been successfully prepared by using successive ionic layer adsorption and reaction (SILAR) methods under a normal environment. The optical properties of as-synthesized NPs and NWs are characterized by using different techniques like photoluminescence (PL) spectroscopy and UV-Visible (UV-Vis) spectroscopy. The structural and morphological properties of prepared morphologies of ZnO were investigated by Xray diffraction (XRD) and scanning...
