Resonance Raman mapping as an interface phonon probe in Si-SiO2 nanocomposites
Ekta Rani, Alka Ingale, A. Chaturvedi +2
Intermediate frequency range (511 - 514 cm-1) Si phonons in Si-SiO2 nanocomposites are shown to have contribution from both core1 and surface/interface1 Si phonons, where, ratio of…

One step growth of PVP spheres embedded with nearly monodispersive CdS nanocrystals using chemical bath deposition
Alka A Ingale, Rahul Aggarwal, Ekta Rani +3
We have used simple chemical bath deposition technique to grow nearly monodispersive CdS nanocrystals in PVP matrix. Systematic study of variation of growth parameters has revealed…
