Effect of Schiff base ligand on the size and the optical properties of TiO2 nanoparticles

Structure, cation valence states and electrochemical properties of nanostructured Mn3O4

“…Thus the IR study indicates the presence of Mn 4 þ ions in the material which could be due to cation vacancies in the sample [18,36]. The peaks observed at 524 cm À 1 and 646 cm À 1 correspond to the distortion vibration at octahedral sites and the characteristic tetrahedral stretching vibration respectively [8,9,29,[33][34][35]. The absorption band at 577 cm À 1 is close to the reported value for Mn 2 O 3 [15].…”

“…The result of EDX analysis ( Fig. 3(b)) shows the presence of only Mn and O ensuring the absence of any impurity [29]. [15].…”

The role of Ag in (Ag,Cu)2ZnSnS4 thin film for solar cell application

“…Since smaller XRD peak width indicates a larger grain size [39], Sample CZTS shows slightly narrower XRD peaks than Sample ACZTS suggesting that Sample CZTS has a larger average grain size than Sample ACZTS [24]. respectively.…”

Urchin-like m -LaVO 4 and m -LaVO 4 /Ag microspheres: Synthesis and characterization

“…It should be noted that a mixture of m-and t-LaVO 4 can be obtained when the pH N 2. The grain size calculated on the (120) diffraction maximum from the half-width of diffraction peaks using Scherrer's formula [40,41] was found to be 60 nm. Fig.…”
