Sol–Gel Grown SnO2 Nanoparticles: Evaluation of Structure, Morphology, and Raman Spectra

Ultrastable Cycle Stability of SnO2 Quantum Dot Embedded Polypyrrole Anode for Li-Ion Battery

“…Figure (d) illustrates symmetry-allowed Raman modes at 496, 619, 673, and 732 cm –1 corresponding to E g , A 1g , A 1g , and B 2g modes of tetragonal rutile SnO 2 . − The low relative intensity of another allowed Raman mode, B 1g , as compared to that of the A 1g mode, explains the absence of the B 1g mode in our sample . The bands at 558 cm –1 arise from surface-related defects of quantum dots, and it is mentioned in previous literature that the peak position of the defect band depends on the size of the QDs. , Generally, in the case of nanoparticles smaller than 7 nm, peak shifts and broadening are observed in the Raman bands .…”

Optical, Dielectric and Structural Properties of SnO2 Nanoparticles Via Sol-Gel Method

“…L.R.B.Santos discusses the preparation of tin oxide by using a surface modifying agent and its surface properties [18]. Saad Saber Abbas reported the structural and optical properties of tin oxide nanoparticles by sol-gel method [19]. The present study discusses the successful preparation of tin oxide nanopowder and its optical and dielectric properties for antireflecting applications and insulating material in electronic devices [20].…”
